3) Yes, it sounds like you are already automatically a Resident Alien for 2017.
TurboTax is not able to do tax returns for Nonresident Aliens. It would really be in your best interest to go to a tax professional that is EXPERIENCED with Nonresident Aliens for your 2016 tax return. They will be able to help you to figure out if the First Year Choice would be a good or bad option to make.
