As a F-1 visa holder, you are
considered as "exempt" meaning not counting days for five years
starting from the date of your first arrival in the United States. After
the five years period, you will start counting days by using the Substantial Presence Test SPT to see if you qualify to be
treated as a US resident for tax purposes.
In default, you are considered as nonresident for the tax year of 2016. As TurboTax does not support the Form 1040-NR, you are advised to use our partner, Sprintax to complete your filing.
However, you do have another option. As you changed to H-1 visa in October 2016, if you anticipated you will be staying in US for at least 183 days or meet the SPT in 2017, you can make an election of First Year Choice to be treated as a resident from October 1st till December 31, to make yourself a dual status alien. ( January-September, nonresident reporting only US source income and October- December, resident reporting worldwide income)
