Some amended returns were taking over 16 weeks back in 2019, then with the mail backlog from 2020, unless the return gets lucky and winds up on the top of a stack somewhere, Id be surprised to see anything about it until the end of summer.

I saw another preparer in a different group say one of their amended returns they mailed in, the client got  a letter letting them know the IRS has it, but not to expect it to be processed until the end of November.
