I have messages on for Icloud Backup for my Iphone but I do not see them in my Icloud. I does show they are using storage but not available to view.
Why do I not see the messages or have the ability to recover them
You cannot view anything in iCloud Backup. You can only use a Backup to do a full restore or to set up a new device. See: Restore your iPhone, iPad, or iPod touch from a backup - Apple Support
If you are referring to the Messages in iCloud option rather than iCloud Backup, see the following from Use Messages in iCloud - Apple Support
You can use Messages in iCloud on your iPhone, iPad, iPod touch, Apple Watch, and Mac. For your privacy, Messages in iCloud is end-to-end encrypted, which means you can't view or access Messages online via browser.
