After you file

@Dulce1989 while the WMR and WMA may say to call; the IRS website site says "don't call"...it's really a waste of time as they really don't know much, 80% of the calls are not answered currently and if you can get through the hold times are quite long (and then you normally are only told what the website says in any event).

 

My recent experience with an amendment was a 12 month (no kidding) wait from May, 2021 to May, 2022.  Things are probably not as bad currently, but I'd still set my expectation at a 9-12 month wait.  

 

The IRS states they are committed to get back to normal processing times by the end of the year so they can enter the next tax year with normal backlogs.  We'll see.
