I have an out of state rental property operating at a loss. How do I reflect this on State return?
Look at your actual Schedule E to see what the bottom line income/loss from your NY rental property is on that form. The amount will be reported on line 21 under the column that matches your property address. That is the number that should be reported as your NY rental income/loss if your only NY income is due to the rental property.
Since you are using the CD/downloaded Premier version of TurboTax, you can click Forms in the upper right corner to view the Schedule E.
