Yes, the 2019 Form CBT-100S, Sch C is very confusing at this point.  Schedule indicates on top "must match amounts reported on Schedule M-1 of the federal return", yet Line 8 clearly indicates that it must agree to NJ Sch K, Part II, Line 8 (which is NJ "taxable income").  The Sch C is locked into the Sch K, Line 8 amount and you are forced to make adjustments in screen 31.1 to reconcile back and get to the correct book income figure.  I spent over 2 hours on the telephone over 2 calls with Lacerte support.  Apparently, NJ made this change late in the game and Intuit hasn't put in a fix for it, hence the mess that we have in its current state.  I hope Intuit cleans this up for 2020 forms.
