Thanks for responding, after re-reading the IRS instructions I ended up removing the at-risk loss carry forward altogether and filing without it, so I can't provide a diagnostic file.
This section was quite confusing, the form 8995 showing "qualified business loss carryforward" total that shows cumulative losses from the past 3 years let me astray, I assumed I needed to fill those in. But reviewing past returns made it clear those losses were already deducted, so I think I should have stayed out of that section entirely.
