LAW and 8962 - They should not have issued a CP12 See BELOW:
The American Rescue Plan Act of 2021, enacted on March 11, 2021, suspended the requirement to repay excess advance payments of the premium tax credit (excess APTC) for tax year 2020.
If you already filed a 2020 return and reported excess APTC or made an excess APTC repayment, you don’t need to file an amended return or take any other action.
Again, IRS is taking steps to reimburse people who filed Form 8962, reported, and paid an excess advance Premium Tax Credit repayment amount with their 2020 tax return before the recent legislative changes were made. Taxpayers in this situation should not file an amended return solely to get a refund of this amount. The IRS will provide more details on IRS.gov. There is no need to file an amended tax return or contact the IRS.
