The IRS does not care if you take the RMD from each 1099-R account or if you take it all from one of your 1099-R accounts.
TTax does not report any of the RMD information to the IRS.
You do not actually show an RMD amount on your return.
The Financial Institution or plan Administrator of your 1099-R accounts must report the year end Fair Market Value to the IRS, and should also report the FMV to you as well.
It is up to you to determine what your total RMD amount is for all of your 1099-R accounts. Then you need to determine if any distribution(s) that you take (or would normally take) each year is equal to or greater than the total of your RMDs.
An RMD amount is not required to be taken from each/every account --as long as the total of all distributions from all account distributions taken, is equal to or greater than the RMD you don't have to take an RMD from any given account. Just say no distribution was taken.
TTax only presents the RMD questions to ensure that you are aware of the requirement to withdraw the RMD.
