Does anyone have the answer?  Need to amend a 2020 return to ADD income to Sch C.  Original return was filed BEFORE the premium tax credit repayment exclusion went into effect.  I know we don't have to amend just because of the PTC exclusion BUT I need to add income to the return.  Should I amend as the original return was filed leaving in the PTC payback or should I amend without the PTC payback.? Client has not yet received a refund or letter from the IRS indicating that they have changed the return for the PTC payback.
