Taxes paid refund
I recieved regular unemployment of $5790 and paid $579 in taxes on unemployment I filed my taxes before March 1, 2021 I received my refund of $1,193 then a few months later when the IRS started doing the recalculating of returns because of the new unemployment rule I recieved $173 in my Bank account but as of today I still have not recieved a letter about why I received the extra refund. Now my question is if the $5790 unemployment I recieved became nontaxable what happened to the $579 in taxes that was paid on the unemployment?
