You became a "Resident Alien" in 2016, and are still a Resident Alien.
That means you can use TurboTax to file your tax return.
That also means that you are subject to FICA taxes, so you can't get a refund for those. A possible exception is if you are ALSO paying Social Security taxes on that income to your home country, and that country has a Totalization Agreement with the US.
