A repayment of a January 2020 distribution that would be an RMD were it not for section 2203 of the CARES Act is permitted to be repaid under IRS Notice 2020-51 only to the distributing IRA. You are not permitted to make the repayment to a different IRA. After making the repayment to the distributing IRA you can do a non-reportable trustee-to-trustee transfer of any amount you wish from one IRA to another.
