I just learned today that IRS announced April 9, that it was going to allow return of RMDs taken before the passage of the CARE act that cancelled the need for 2020 RMDs. Well sorta. 2020 RMDs taken from Feb 1 forward can be returned by July 15. No relief (at least as yet) for January RMD withdrawals. However article said further action by IRS is still possible.

The above source may be behind a paywall.
Also, there is still the 60 day window that will allow you return any RMD withdrawals without penalty.
I did a significant in-kind transfer in early Feb so this will allow me to move the shares back. Interesting wrinkle for in-kind, if you took shares you have to replace shares. Does not matter what current price is so if you already sold out your RMD shares transferred, you probably can replace for a net gain. YMMV
