I have never used Turbotax Business. I've only used pro software - many different versions depending on the vendor (yes some vendors had different versions of pro software ) - for over 50 years. the reporting of excess distributions as far as I can remember has not changed and some versions were "smart enough" to place excess distributions in the OAA columns others required manual entry. from what I gather there is no support for TTB. with pro software came the ability to actually talk to the programmers when issues arose and issues do arise even with pro software that costs tens of thousands of dollars
