Object moves differently in Timeline

Unity Engine
1

When I added a timeline to my player, the player will not move around the screen like it did without a timeline. I am new to Unity, please help if you can. I tried to attach a video, but it didn’t work.

What is happening is that I can move my player all around the screen when the timeline ends, but while the timeline is playing my player motion is restricted.

If the timeline is animating the player character, it will in most cases overwrite any motion the player character made .

That isn’t happening for any of my classmates who are doing it in the same format.
