Mine can not be combined as one of the "duplicates" was a ROTH conversion and the other a normal distribution. They can not be combined as the ROTH conversion amount can not be included as an RMD distribution.
The tax withholding on each 1099-R was different and therefore should not have been flagged as duplicates.
I am unclear if it is the IRS or TurboTax that is flagging this as an error. Regardless, one or the other should fix the problem
