Which screen did you use to enter the rental income and expenses?

Do you have F.8825 for these rental properties?

Do you see the rental income being report on Line 2 of these K-1's?

Don't believe any of the input fields on Schedule K > Rental Real Estate can trigger reporting on Line 16.  Instead, entries for Line 16 are made on Schedule K > Other Schedule K Items, on the Less Common Scenario tab.

You may want to double check your input.
