In June of 2017 I moved out of NJ and have been traveling abroad since. How do I file without a permanent address? Do I file a partial year NJ return?

While traveling abroad I have earned very little income, $50, through an online Etsy shop, but other than that I have not earned any money. I am traveling, so I do not have a permanent address abroad or in the US. How/where do I tell Turbo Tax that I am not living in the US and that I do not have a permanent address? Do a file a partial year NJ tax return and nothing for the rest of the year?
