I had the same situation as you. I did my 2020 return February 10th got my refund in March. I was given the wrong information about the recovery rebate and added the money on my return as if I got it for my son but I didn't my ex wife did so I amended my return May 16th. Received a direct deposit July 28th for the amount I out in my amended return. Got a CP2B notice from the IRS August 9th explaining that it was for both my unemployment rebate and the child tax rebate. Also, amended returns don't fix the unemployment taxes so it can't be addressed in your amended return anyway. Hope this helps you if you're still looking for an answer
