ACA Tax Credit Forgiveness

I have already filed my 2020 taxes. I have not received my refund yet. I took advantage of the ACA Marketplace subsidies and I underestimated my income - so, I had to pay back the overage credits. According to the newly passed American Rescue Act, I no longer own this payback. Will I need to refile or amend my completed return? Will Turbotax help with this?
