There is no fee for amending your return. If amending gets you an additional refund, then go forward with amending and get the refund. An amended 2021 return will have to be sent in by mail.
You should mail it by using a mailing service with tracking like certified mail so that you know it was received, since you will have a long wait for it to be processed.
