Since RMD requirement is waived for 2020, I would indicate None was RMD. It does not effect the taxability of the distribution. The "Let Us Know" relates to your state return and if there was a RMD requirement on your state tax return.
Because of a law change on March 27, 2020 as part of the CARES act, required minimum distributions have been suspended for 2020. This applies only to your Federal tax return, the rules in your state may vary.
Therefore, if you live in a state that did not couple with the Cares Act and would still requires RMD, then you would want to include your distribution. I could not find this in any state.
