Repaid my CARES Act / Covid IRA Distribution in December 2022, but did not check box 9 or 17 on 2020 form, Now what??

Question:  I took $20K out in Dec 2020 under the CARES Act and filed a 8915E form. I chose the taxable spread over 3 years. In the 3rd year (2022), I paid it all back in December 2022.  But, I did not check box 9 or 17 on the 2020 8915E form.  In turn, it shows I owe the third installment and I guess I would put in for a refund of taxes in 2023 filing???

 

How can I correct the 2022 8915-F form to show FULL repayment? It looks like I have to go in and amend 2020 and check box 9 or 17, not sure what to do with 2021 amending and claim repayment on 2022 form?   APPRECIATE the guidance!  Ty.
