That was the whole point of the discussion between Banner & the Ancient One. She was saying if she gave up the Time Stone, the split timeline would have no defence; Banner's suggestion was returning it would prevent that timeline's existence.

Every single Infinity Stone involved in the Time Heist was returned, therefore eliminating that part of the timeline, with the exception of the Tesseract in 2012. This is my last message, than i'll move the conversation here: https://marvelcinematicuniverse.fandom.com/wiki/Thread:267680#8

​​​​​​Returning the stone where they belong does not repair a split in time. For example, the timeline where Loki escaped is changed no matter if the Time Stone and Mind Stone are returned or not. What it repaired is the possibility that the Ancient One's own timeline will not have a terrible future where the Time Stone is lost and terrible thing will happen to space and time. But the Ancient One's own timeline is already separate from Banner's time line because of the Avengers' own time travel jump. Thanos cannot be eliminated from the existence by killing him as a child in the original timeline, and for the same rule of physics Thor cannot spoke with his own version of his mother from his own Timeline in the past.
