Locked email after migrating to new iMac

I have been locked out of one of two apple email accounts after migration to a new iMac running Sequoia. Three days ago Apple told me I was locked out for 3 days and that they would send me a notice after that period. I attempted the recommended work around with not success. I have not received any notice.

Both emails were added in the @Mac era and were both with the same Apple ID and password (password has been changed several times since)
