Hi sfb71,
welcome to the Apple (user-to-user) Community!
Re: "Accessibility Shortcuts window came on. I can not find a way to turn it off.

(Am no expert in this area: You may just need to click on the window to highlight it, and press "escape" ?)
Else:
Wondering if Apple Support's online Apple TV User Guide may help at all (link below):
There is a "Table of Contents" link on the "welcome" page that opens from the link below:
If you are not using tvOS 17 (which is the newest version):
For accurate info.: You can choose your Apple TV's tvOS version at the top of articles:
Apple TV User Guide - Apple Support
For more support if needed:

All the best :-)
