For 2020 only, the American Rescue Plan Act suspended the requirement to repay excess Advance Premium Tax Credit. If your Form 8962 would show a repayment, the IRS instructions are to omit Form 8962 from your tax return. TurboTax will not produce Form 8962 if it is not needed. Form 8962 is only needed if you have a net Premium Tax Credit (additional credit owed to you). If there is no amount on Schedule 3 line 8 of your tax return (or if Schedule 3 is not included), Form 8962 is not included in your 2020 tax return.

for 2020 it will not show up in the forms required to be file if you received excess credits that normally would have to be paid back. a tax law change for this year removed the repayment requirement. on the other hand, if you were entitled to an additional PTC the form is required and the credit will show up on schedule 3.
