How to Reverse 2020 RMDs as permitted by the Cares Act

I want to take advantage of this:

to avoid all 2020 RMDs. But it is a bit confusing.

I previously set up monthly installments based on the IRS life expectancy tables and they are still coming monthly.

I would like to reverse/avoid all RMDs this year. But the procedure seems unclear.

If I cancel monthly installments then I can never reinstate them, I can't find where that has changed.

The RMD change seems to imply that I can roll over the RMDs back to the TSP using Form TSP 60. But other documents say that installments based on the IRS tables cannot be rolled over. Has that rule been repealed for the year 2020?
