I don't operate in a Windows environment so can't see what TT is actually doing.
However:
- Sch M-1 line 9 is net income for line 1 at the top of page 5 "Analysis of Net Income".
- Sch M-2 is book income
- So Sch M-1 line 9 most likely does not equal Sch M-2 line 3
- It is subtracting guaranteed payments, because if you look at the actual Sch M-1 line 3, guaranteed payments are added to arrive at a figure on line 5 of Sch M-1. Appears TT is appropriately subtracting the guaranteed payments in order to avoid double dunking the guaranteed payments; because most software back into Sch M-1 line 1 which already has subtracted guaranteed payments.
- Just a confusing analysis.
