CARES RMD Repayment

I took my RMD for this year back in January 2020. I have two IRAs and took the  yearly required amount from one of them. I would like to pay the money back (According to the CARES act) but not into the IRA I took the money from, but into the other IRA which is handled by a bank. Can I do this or does the payment need to go back into the IRA it was originally taken from?
