It seems because of the Cares Act, Turbotax in its current status can't handle the case where a 1099-R form box A include both amounts that was converted to a Roth account and the RMD that was reverted back to the IRA account from which it was distributed in the first place. Either our brokerages issue two corrected 1099-R forms, or Turbotax finds to way to deal with the situation in its future updates.
