Hi amhartl,
Welcome to the Support Communities!
I would first suggest going to the My Apple ID website to review or update your settings.
Apple ID: Changing your Apple ID

Apple ID: What to do after you change your Apple ID

If you changed your iCloud account, you will need to delete the account and then add the new Apple ID and password.
iCloud: Change iCloud feature settings

Depending on whether you want to stop using iCloud on all or only some devices, do one or more of the following:
On your iOS device’s Home screen, go to Settings > iCloud, then at the bottom of the screen, tap Delete Account.
Note: If you delete your iCloud account, iCloud will no longer
back up your iOS data. You can still back up your device in iTunes (for more information, open iTunes and choose iTunes > Help).
On your Mac, open iCloud preferences, then click Sign Out.
On your Windows computer, open the iCloud Control Panel, then click Sign Out.
Cheers,
- Judy
