@anomymous , generally if you came in as a F-1, you are considered an exempt person ( from counting days present towards SPT ) for five calendar years including the year you entered. So when did you first enter US with F-1 ? Was this your very first entry with three prior years ?
Note that if you are still NRA then you will have to file your return on form 1040-NR ( not supported by TurboTax -- use SprinTax or similar services or tax professional familiar with international taxation ).
BTW -- which country are you from ?
And yes generally NRAs use W8-BEN and therefore receive a 1042-S.
