I spent all year outside of Jersey, though it stayed my mailing address. I actually lived overseas working for the US government, meaning that I still need to pay federal taxes. However, according to "Who Must File" from NJ State Department of Taxation, I need to file a "non-resident" return since I met all three factors 1) did not maintain a permanent home in Jersey 2) maintained a permanent home outside Jersey 3) spent less than 30 days in Jersey. 

I am struggling to indicate this on the Turbotax software. How do I do this? I successfully did it last year and received a tax refund for all the state NJ taxes that I paid all year. This year I don't see where to do it.
