After you file

It's not clear, but I hope you did not submit an amendment with incorrect amounts.

 

IRS has a separate form you use to change your mailing address.

 

There's a trick to change your address with 1040-X but IRS probably frowns on it and no guarantee it will work.

Also, IRS is currently three months behind processing 1040-X.
