I filed a Form 1045 for a Personal Loss  Loss Carryback for the 12/31 2019 year end  last December, 2020. I have not heard back from the IRS. I called the IRS and they said it was not on the System yet, but I shouldn't worry because they may have not gotten to it yet. Should I refile on an Amended Form 1040? The First year that I would it back to the Taxpayer already had a loss so do I have to file that year or can I just file the next year where the taxpayer would derive the benefit?

The length of time seems extraordinary even for the IRS and
