Do I use a neg or pos number to indicate loss when the line is asking for loss? "Rental income (loss)" Pos number nets me more refund :/

I'm entering data for Schedule K-1, in field 20 I have an N and Z code.  Turbotax is asking me about it.   Code Z is called Section 199A.   Turbotax is asking, "We need some information about your 199A income".   I checked that my business has income (loss) and then specifically there is a line for Rental income (loss) with a box after it.   Do I put a positive number in here considering this number is already designated a (loss) or should I put a negative number here?   When I put a negative number, I end up owing more money, so it kind of confused me.
