Maryland Net Decoupling Modification

I'm using TurboTax Deluxe Desktop and I have a MD K-1 from a pass through entity (LLC) that has an entry in Section B. Additions, Line 3 "Net Decoupling Modification".  I expected TurboTax to ask for this amount and automatically create the 500DM form for Decoupling Modification, but it isn't.  Does anyone know where I should enter this number to have TT create the 500DM form?

Thanks,

Rich
