Investors & landlords

I do not have anything negative to report! That is my point! For some reason Turbo Tax is saying I do. There is not one negative number on my 1099s or inputted into my return. I have cleared and re-entered the information  manually twice now and re-imported 3 times. I have completely cleared and deleted my return starting over using various methods 3 times now. Every time it says I have negative cost basis. There is no negative anything.
