I can't answer for IIIHeroic, but I'm having the same problem.
In my case the 'exception field' is checked because I'm summarizing multiple transactions, as suggested by TT when submitting summarized data. I clearly state that the basis _has_ been reported to the IRS, but when TT prints the 8949 form it checks box C the 'not reported' -- should be box A
How do I correct this?
