I've looked at one of my clients  F1040 w K1 from F1065  , I was able to create the message you are getting.   Sec179 is greater than income which can only happen if you have other business activity that has a loss greater than income on the K1    or   the F1065 that the K1 was issued from was not done correctly.   Is K1 income greater than line 12 Sec179?
