After you file

wait for the IRS to process the unemployment compensation deduction, they may adjust for the proper PTC. However, I think this is something the IRS should be able to adjust for without the need to file an amended return. 

 

from the IRS 4/9/2021

If a taxpayer paid an excess APTC repayment amount when they filed their return with Form 8962: Individuals in this situation should not file an amended tax return to get a refund of this amount. The IRS is taking steps to reimburse taxpayers who filed Form 8962, reported, and paid an excess advance Premium Tax Credit repayment amount with their 2020 tax return before the recent changes made by the American Rescue Plan Act of 2021. Individuals in this situation should not file an amended return solely to get a refund of this amount. The IRS will provide more details soon
