HI, if purchased from a Domain Provider (example: GoDaddy), you need to search their support pages.
example: Godaddy
https://www.godaddy.com/help/transfer-my-domain-to-another-godaddy-account-822
If purchased with Square, you can try to contact Customer Support with this link. Monday to Friday, 6:00am-6:00pm PST.
Contact Customer Support

You will get a few options to contact, click Call Us, a new browser window will open with phone number and customer code.
You must be logged into your account and is best on a laptop or desktop. Phone app sometimes displays unavailable at times.
Hope this helps.
