Well, the IRS is wayyyyyyyyyyyyyyyyyyyyyy behind. I file my 2020 tax return in Feb and had to pay. I checked the box to setup a payment paln. Something didn't seem right. One of my w-2 just didn;t seem right. I worked only parttime but the amount earned was way tooo much. After several months of dealing with that employer, they finallly issue a new w-2. It changed my taxes drastically. Now, mind you, still haven't heard anything from the IRS about the payment plan. I filed an amended return in July and sent a small check as a payment plan was no longer necessary. The check was cashed in August and the IRS sent paper work to set up the payment plan, (minus the amount I had just paid) ??????? So, they took the check but didn't process the amended return. I assume by now they have, as I haven't heard anything else about the payment plan.
