Amend 2020 return for Covid Rollover

I repaid (rolled over) all of my Covid distribution in 2021 after my 2021 tax deadline. I am attempting to amend my 2020 return to get the taxes that I paid on the distribution refunded. I can not figure out how to correctly report the repayment and if I am supposed to change anything on my 1099R. All question in the Turbo Tax software regarding repayment of the distribution are in regards to if the repayment was done before my 2020 tax filing deadline. I am really at a loss on how to amend for this situation.
