Where to enter MA differences to Federal K-1 box 2

My Federal K-1 (1065, for partnerships/LLCs) has one value; the corresponding MA 3K-1 line has a different value.  I need the different value to show up in the MA form 8582 part V for passive activity losses.

 

However, in the MA section of TurboTax, when I edit the K-1 and for "Do you have any Massachusetts differences?" I select Yes, the only differences I can enter are for the "partnership income", and are reflected in Schedule E, rather than Schedule 8582.

 

How can I enter a MA difference to a federal form 1065 Schedule K-1 box 2 "Net rental real estate income (loss)" so it shows up in Form 8582 Part V (passive activities), modifying a PAL, and not as (taxable) income?
