While according to Markus & McFeely, time is only changed if you mess with one of the infinity stones, otherwise it's the predestination paradox. I think I lean more towards Markus & McFeely's explanation, as it works better with the conversation between the Ancient One and Bruce as well as with how the movie resolves the timelines.

If a new branch timeline is created every time someone travels into the past, then returning the stones wouldn't actually result in those timelines disappearing, it would just create two seperate branch timelines, one where a stone was returned and another where it remained absent.

Again, Bruce specifically instructs Steve to return the stones to the exact moments that they were taken in order to prevent any more branch timelines from forming.
