I'm new to the animation part, and I don't know if I messed with any settings I shouldn't. When I move the animation timeline, the camera is zooming in and out. I noticed that the camera parameters tab was marked with these red squares. How do I make it stop zooming in on the animation?
The red highlighted spinners next to FOV field indicates it is currently animated which is why you are seeing it change. This could have happened if you accidentally had Auto Key on and were playing with the FOV settings. To fix this, make sure auto key is off, select the camera and then in Animation menu "Delete Selected Animation".
