You can't see what's backed up to iCloud. You can only see that a backup has occurred. You can check in Settings>Apple Account>iCloud>iCloud Back up. About midway down the page, you'll see the time of the last successful backup.

This article outlines the categories of data that iCloud backs up:

What does iCloud back up? - Apple Support

Note that anything you sync is not part of the backup.

Perhaps if you explain why you're asking, you can get more information about how to do what you want.

Hello Marcia

Simply go here and sign in with your Apple Account https://www.icloud.com/

The transition from Apple ID to Apple Account is now fully implemented, and users can still sign in with their existing email address or phone number and password. While the term "Apple ID" may still appear in older documentation, the current official name is Apple Account.
