I had a large tax liability in 2021 due to capital gains which I do not expect in 2022. It's causing ridiculous estimated tax payments in 2022

I had a lot of capital gains income in 2021 which I do not expect in 2022.  I made my estimated tax payments in 2021 as the income was realized.  I'm expecting a sizeable refund due to overpayment of taxes in 2021.   TurboTax is telling me that I now need to pay 110% of the 2021 tax bill in 2022, and it specified a huge amount of estimated taxes.  Again, I do not expect to earn the same level of capital gains in 2022.  If I pay the specified estimated taxes, they would all be returned at the end of 2022.  This seems nonsensical.  Do I have any recourse to pay what I actually expect to owe rather than the 110% figure specified by the IRS?  Is it a law, or is it a guideline?
