For 2021, my understanding is that excess advance payments of PTC are to be paid back in 2021 (in 2020 they were waived).  However, in the Proseries Basic software, I have a situation where line 25 (Advance payment of PTC) exceeds line 24 (Total Premium tax credit).  That difference is supposed to go to LIne 27 (Excess Advance payment of PTC) and then to Form 1040.  However, in Proseries Basic for 2021, line 27 is blank instead of showing the excess.  Can someone help explain to me why?
