Whenver I move my application from one screen to another my timeline stays on the original screen?? I want to pin it to the application not run it as a separate application. How do I pin it to the stage?
You don't "pin" windows in Animate, you dock them. Just drag the timeline window up to the top of the main window until it snaps into place. Then select "Lock" in the timeline's hamburger menu to prevent it from ever being accidentally undocked.
