I just spent over 1 hour with Proseries Support trying to figure out why my client's Form 8962 and Schedule 2 disappeared (I updated Proseries today). After over 1 hour, it turns out that this has something to do with today's Proseries UPDATE 4/7/2021).
I will be holding off on finalizing this clien'ts return until Proseries is working properly again.
Please be aware. After your enter Form 1095-A, Form 8962 should open up, then Schedule 2 might be added automatically if repayment of PTC applies. Schedule 2 Line 2 is the Excess advance Premium Tax Credit Repayment that links to Form 1040 Line 17.
