Where should I find Apple TV menue with movies?

I can't find the menue with movies on Apple TV site.

MacBook Air 13", macOS 10.13

To find movies from the iTunes Store on you MacBook Air, macOS High Sierra 10.13, use iTunes.

To find movies from the iTunes Store on you MacBook Air, macOS Catalina 10.15, use the Apple TV app.

To find Apple TV+ content, use the Apple TV app and find the Apple TV+ channel in Watch Now, or watch on tv.apple.com.

A few users have reported seeing only an empty library in the Apple TV app. Is that what is happening with you?

I was charged already for the first month.

Charged for what? Apple TV+ perhaps? When did you sign up? When was the charge?

Apple TV+ has a 7 day trial period, after that subscription fees per month, payed in advance. Thus per day 8.
