Thanks for your considered response. 

The only override diagnostic was from the "Automatic Apportionment" checkbox.  Unfortunately, the only change provided by that box is if I put a 2 (no automatic apportionment) the amount in the Utah column is the same as the Federal column.

Now I'm wondering if it's because I have one resident partner, one part-year resident of Utah, and two non-resident partners. (The two non-residents have claimed the waiver as they have other Utah income). Would that make a difference because the residents need to pay tax on their entire income? That's how California would work (but there's a source income column on the K-1).

Back to the instruction booklet.
