Error in Software on Form 8960?

Hello! I think there is a possible error in the software.

Facts:

* Schedule C income + Rental income #1 + Rental loss #2

* Rental income #1 and rental loss #2 are from short term rentals with material participation (nonpassive income)

Issue:

All three of these are going net to NIIT line 4a. However, for line 4b only Schedule C income and rental income #1 are flowing through. The loss is not going through from rental #2 (i.e. it is not netting with Schedule C and rental income #1).

I made rental loss #2 income and it does flow through then. Why is the program not netting the loss on 4b? I read the IRS publication and it seems like it should flow through as well...

To take a closer look at this situation if would be helpful to have a diagnostic copy of your tax file experiencing the issue.

Thanks so much for the response! I was on the phone for 2 hours yesterday and got this escalated for the developers to look at, so I think it is moving in the right direction. There is a workaround where I can just enter in the adjustment myself in the worksheet mode so it is more of a "heads up."
