Investors & landlords

Hi, my K-1 shows two entities under Line 20 Z, but one of the two entities shows $0 for every line item; I'm assuming I don't need to enter this information.  The 2nd entity show some data on two line items (see below).  I'm assuming I would have to add these numbers (-$11 and 287).  Does this mean I only file one K-1 line entry for this in the "Enter Box 20" info (2nd image below in turbotax online) ?

Also,

I see this note that lists several states with activity.  Do I need to file a separate state tax filing for each of the states below?
