Minnesota gross income - K1 and Nonresident

[UMDJeremy]

Have a return where client has a K-1 from a partnership in Minnesota (is a MN nonresident). The PTE tax was paid on behalf and shows on the K-1. Lacerte was calculating no tax due because the net income was less than $12,525. However that seemed wrong since K-1 showed gorss income line 36 of ~$13000. There is an info diagnostic ref #1756, however that just says you need to file because it's less than the gross # and to collect a refund. 

However I found there is an input box on K-1 screen (screen 20 code 312). Once I put the ~$13k # in that box, the tax was calculated on the return as is correct.

There should be a critical diagnostic that if you have a K-1 input with MN source #s this field is required or to input -1 in the field if none on the MN KPI form.
