When to return the Space Stone?
As far as I understand there is no concept of multiple timelines in Avengers: Endgame. So when Tony and Cap are trying to bring back the Infinity Stones with the quantum tunnel, Tony lost it and Loki opens a portal and disperses. Doesn't that make the past more complicated (altered plot opposed to what was supposed to happen [Thor taking him back to Asgard and so on...])? Even if Cap takes back the Space Stone in the past, at which exact point in the timeline should Cap take the Space Stone to make the mission successful?
after Loki is gone. That would make 2 Space Stones in the past (not possible logically), one with Loki and one with SHEILD agents.
before Tesseract was handed over to SHIELD agents. Cap would have to face 3rd of himself, one from the past, one from the future who is bringing the Tesseract back to the future to destroy the stone.
It makes no sense as to how the Space Stone is returned.

Cap returned the Tesseract to 1970. The bit with Loki 2012 stealing the stone seemed to be mostly comic relief.
I suspect that Thor 2012 caught up with Loki 2012 and returned the Tesseract to Asgard. This scenario is compatible with the timeline as we know it.

How was the Space Stone returned?
At the end part where Cap returns the stones, it is shown that the Space Stone is not in the Tesseract form. We know in Infinity War Thanos crushed the Tesseract to get the Space Stone - so the Avengers ultimately did the same when they got it from 1970.What year do Tony and Cap go back to?
After their mission in New York resulted in an alternate Loki absconding with the Tesseract, Tony Stark and Steve Rogers went to 1970, as both the Tesseract and Pym Particles needed in order to return to 2023 were housed at Camp Lehigh at the time.Did Captain America return all the stones?
At the end of Avengers: Endgame, Captain America completed an important mission: he returned each Infinity Stones to their respective points in time, making good on Bruce Banner's earlier promise not to disrupt the timeline.What happened to the Space Stone after Captain America?
Following Schmidt's defeat at the hands of Captain America in 1945, the Tesseract fell into Arctic waters, where it was recovered by Howard Stark. The Tesseract was then kept at Camp Lehigh in New Jersey, where it remained until at least 1970.How Captain America Should Have Returned The Stones

Answer 2
The space stone was returned to 1970 - this is the location in time that the space stone was taken from so this is where it was returned to.
The entire Loki incident in 2014... - you're assuming that the timeline in 2014 is different. We don't know that these events didn't originally happen because they occurred off screen at the end of Avengers Assemble. If these events didn't originally happen that no doubt this is the introduction to the Loki TV series and it will be explained further there.
Answer 3
If you'll recall, Steve and Tony went back to 1970 in order to get A) the Tesseract, and B) more Pym Particles. This happened because Loki took the 201x version. As a result, the Tesseract that went missing in 201x is not the one that Steve will be replacing.
Answer 4
Everyone keeps forgetting one KEY rule of the marvel time travel: you CAN'T alter the past, because it is your future.
Let me explain how it works.
Your time ALWAYS goes forward, it never goes back, because you travel in time (remember what happen when time travels in you, right?).
So if you "go in the past" you are always going in your future (I know it's complicated).
Let's suppose Cap return for last the space stone in the 70s and then, as the movie portraied, stays there with Peggy. He will NEVER see in 2012 another version of himself that "come back" because he is now in his "new" future and he will not come back again to take no stones. The "future Cap" (the one that now is frozen in ice) will do it in the future Cap future.
Still with me?
Your timeline ALWAYS moves forward, you can jump back and forth but wherever you will go it will ALWAYS be your future, and so nothing that you do will influence your present.
Does this create forks and alternative realyties? Of course, and I think tath the Loki series on Disney + will show us the adventures of the 2012 Loki that run away whit the space stone.
One last thing: it's a MOVIE. Just enjoy it.
Peace.
