Thanks to all who replied.
I'm not an expert in the rules and terminology of Keogh RMDs, but what I'm up against is the RMD requirement for those reaching age 72. I'm not trying to roll over anything, unless I just plain misunderstand the definition of rollover; I'm going to take the RMD from my Keogh in cash and use it for 2022 living expenses. I'd like to avoid tax withholding on the RMD for cash flow reasons - I'd rather pay the taxes triggered by the RMD across four quarterly estimated tax payments than in an upfront 20% withholding.
With all that in mind, I believe that @Bsch4477 got it right in stating that no 20% withholding is required on the RMD. Does anyone see it differently? Thanks.
