1065 K-1 Supplemental Schedule 8990 Partner who may be subject 163(j)

[KDBollman]

I prepare many 1065, especially with the 8825.  Few if any are subject to the Section 163(j) interest expense limitation.  However, there are two partners who are involved in many dozens of the partnerships.  They might be subject to the limitation.  I need to provide their preparer with a supplemental schedule with the last 3 year's gross income and the lines involved in the 163(j) computation.  Lacerte provides a worksheet from the 8990 for the Partners.  ProSeries is questionable.  PS staff can't help me.  Does anyone have that issue, and how do you address it?
