Investors & landlords

Hello. Thank you for the response and yes, I would agree that what I quoted pretty much answers the question.
However, I do not understand why TurboTax says this when I am going through my NJ return:
"Other Non-Wage Income.
Enter any non-wage income you received, including the portion earned or received while you were a New Jersey resident. Do NOT enter income that you previously entered on your FEDERAL return. (This is not common)."

How can you explain this? Because I got confused now.
