Remove phone from Allow Calls on Other Devices

I just purchased a 12 Pro and traded in my old XS for a credit with my carrier. I reset and erased my old phone (XS) before sending and ‘Find My’ is turned off and got an email confirming this from Apple. I even deleted the backup for the XS and removed from my list of devices. It still shows up in my ‘Allow Calls on Other Devices’. I have no idea how to remove this and I’m paranoid that maybe I didn’t reset the phone. It’s not listed anywhere on my iCloud account. I’ve never had this stay on before after clearing and removing an old phone.

I have turned off all of my Apple devices, restarted. I’ve clicked the allow calls on and off and nothing removes my old device. Any ideas?
