Hello jordanne8,
You can access your library in the Apple TV app. Please check out this link, which explains how to access your Library, and may help: Library in the Apple TV app
The Library screen in the Apple TV app includes your purchases and rentals, organized by category.
Note: Not all devices support on-device transactions, so you may not be able to buy, rent, or subscribe to shows or channels directly. However, you can sign in with your Apple ID to watch items you’ve already purchased, rented, or subscribed to on other devices.
Browse your Library in the Apple TV app
1. Open the Apple TV app
on your smart TV, streaming device, or gaming console.
2. Navigate to Library, then browse items, or select a category or genre to filter items.
If you aren't able to locate an item that you want to redownload, please check out this link, which explains what to do in that situation, and may help: If there's an issue when you redownload apps, movies, or other content from Apple
Thanks!
