Timelines rule cannot changed from travel to travel.

From what we saw, a travel to the past (from point A) bring you to a different parallel reality (point B) that can't be altered without affecting the original timeline. The Avengers traveling to New York City in 2012 creating a series of changes that cannot certainly be justified with the Bootstrap Paradox (Loki effectivily escape with the Tesseract, Tony Stark has an heart attack that Stark from point A didn't have). The Ancient One from Point B also speficically states that her reality and Banner reality are separate, and that the Gems must return not because of a time paradox, but because Point B's timeline can be altered negatively without it. Also, every single jump create a separate reality, since in Point B (2012 New York) Loki's escaped, while in Point C (2013 Asgard) Loki's imprisoned after the Battle of New York of that timeline. Same thing can be said for Nebula, Thanos and Gamora of Point D (Morag 2014): the first two without affecting the course of Timeline A. That's why it's not physically possible for Steve Rogers to travel in the past of the same reality where he was frozen in time, because a Bootstrap Paradox is not conceivable with the idea of affecting time.
