No TurboTax has not been updated, because the IRS is still reviewing the information and how the changes will be implemented. We do know that the IRS does not want people to amend their return due to this one-time relief for 2020. TurboTax will implement changes when the IRS has given this guidance.
Here is a statement from the IRS with a link to check for updates.
We’re reviewing the tax provisions of the American Rescue Plan Act of 2021, signed into law on March 11, 2021. Taxpayers who filed a 2020 tax return and reported an excess advance premium tax credit repayment on Line 29 of Form 8962, Premium Tax Credit, should not file an amended tax return only to get a refund of this amount. The IRS will provide more details soon. For the latest updates, check IRS.gov/coronavirus.
