@tinybrooks "I'm wondering how long I should wait before mailing it again"
You should not re-send an amended return. They will eventually process your amended return. If you have not already done so, I encourage you to read through this entire discussion. Probably all of your questions (except the one you really want the answer to -- when will the IRS do it?) are discussed already. Last year I filed my amended return in May. It showed up in the system in about October. I finally got the "all clear" in February of this year. The IRS has not recovered from the backlog created by COVID and by the extra work of handling all the stimulus checks. I advise patience. My son is now caught in a different IRS issue where they flagged his account for additional identity verification, but he hasn't got the right stuff (mortgage, etc.) to qualify to do it via the website, so the website says he must call, and then he's back to the calls never being answered. You aren't alone.
