Hi TuckTucker1014,
To see your trusted devices, follow Use two-factor authentication for your Apple ID on iPhone:
View or remove trusted devices
1. Go to Settings
> [your name].
2. A list of the devices associated with your Apple ID appears near the bottom of the screen.
3. To remove a device, tap it, then tap Remove from Account.
4. If you remove a trusted device, it can no longer display verification codes and its access to iCloud (and other Apple services on the device) is blocked. To add it back, use two-factor authentication to sign in to your Apple ID again.
Note: In this resource, you can also see your trusted phone numbers as well.
If you think your Apple ID has been compromised, follow If you think your Apple ID has been compromised.
If you need further help, contact Apple for support with your Apple ID here Get Support.
Take care.
