Ok ... first the IRS has no solution for your situation except to apply for the credit on the 2020 return. Blame congress that thru this together and required the IRS to implement it at a moment's notice during a pandemic with a severely reduced staff.
Next, don't blame the IRS or TT for your failure to review your return before you filed ... if you had looked you may have been able to correct this ... you all have to take some responsibility for your part in this mess.
Finally ... vent to your congress person to get things corrected if they can since they are at the root of the problem.
