If you deleted the Apple ID, you can't restore it. From the article below.
Deleting your Apple ID is permanent. After your account is deleted, Apple can't reopen or reactivate your account or restore your data. If you aren’t planning to use your account for now but may consider returning to it in the future, we recommend temporarily deactivating your account (where available) instead of deleting it. A request for anonymization will be treated as a request for deletion and follows the same procedure.
