I would GUESS "no".  The PRR pricing shows 1040 and 1040NR under one category, and 1120, 1120-S, 1065, 1041 and 990 under a second category.  So be me, 1040NR is not part of the "business" category.

Does your taking on his client depend on the answer?  If not, just start entering the client, click "print" and see if the program asks you to pay of if it applies the return to the 15 business returns.
