I filed my 2019 return and I mailed it and I would never mail it without paying what I owe. I filed in February of 2019 and I received the return back in July 2019 showing that I forgot to sign it. I signed it and returned it immediately. I received a notice one dated August 7, 2021 that I didn't pay the taxes owed, a fine of $435 is being assessed for failure to file, a $5.39 fee is being assessed for failure to pay and a $40.31 interest charge has been assessed and will continue until the total balance is paid. I looked at my two bank statements and do not see a check being cashed by US Treasury. I didn't make a copy either, for some reason. I will check my credit cards because I might have made the payment with a credit card.
