Question: Why did Vision not appear in the film?
Answer: Short version, because he's dead. Bruce only brought back everyone Thanos "snapped", and Vision was killed before that. Now, whether Shuri managed to finish her work before then, somehow "backing him up" or otherwise separating him from the mind stone, we don't know as yet - it may be they somehow revive him in a future film, or the upcoming WandaVision TV series. But for now, he's gone.
Answer: Technically vision wasn't "killed." He wasn't even alive. He's a robot. Maybe they could have used the mind stone they had to try to revive him, but Thanos ripped out a good chunk of his head already. And they needed to put the mind stone back anyway.
Answer: If you noticed Black Panther's sister had just one connection left with the gem, and who said she didn't download a copy of his Consciousness but didn't finish, due to the snap and the end battle.
Answer: As the guardian of the Soul Stone, the Red Skull presumably just showed Steve the spot where he needed to return it. As for how Steve got to Vormir in the first place, he could have either borrowed a spaceship from Asgard or had Heimdall teleport him there via the Bifrost after returning the Reality Stone.

Asgard doesn't exist at the time Steve would return the stone.
It did when they took it so its still there when he brings it back. It's shortly before the dark elves attack.

Yes it does. Clint, Natasha, Rhodey and Nebula all traveled to Morag in 2014 when Quill took the Power Stone, at which point Clint and Natasha took the Guardians' ship and traveled to Vormir to retrieve the Soul Stone. Steve can travel to Asgard in 2014 and ask Heimdall to teleport him to both of those planets. Asgard wasn't destroyed until just before the events of Infinity War.
