Thanks so much.  It does seem to calculate correctly when entering the guaranteed payments as a negative adjustment to net earnings in Part II.  I don't see where it states that it only does one business at a time, however. The ProSeries Basic instructions state that the computation includes the total of Schedule C & Schedule F net income and Schedule K-1 self employment earnings (which would be applicable and properly included if the SEP plan was set up within the partnership).  Where taking the partnership guaranteed payment amount out of the equation as an adjustment as you suggested works, I will just go ahead and use that method.

Thanks again!
