Hello, the answer I recieved is: "Net rental income for your LLC will appear on Line 2 of Schedule K on Form 1065." and "that number does not factor into the total income on Line 8, which is strictly for trade or business income (unless the LLC is a real estate dealer)."
I believe that I used the figure from Line 2 on the Schedule K from the previous year (if filing for 2020 using 2019's figure) when asked for the "total income amount." I filed with Line 8 on Form 1065 blank since my LLC earned no other "business income" besides collecting rent. I am by no means an expert but this is what I did. Hope that helps.
