F1 Student on 6th year

Hello! I am an F1 student on my 6th year. I need to file tax return.

1) Can I do it through TurboTax? My school directed me to Sprintax, Sprintax told I'm a resident for tax purposes and should use Turbotax.

2) I have W2 and 1042S forms. Which form should I fill out and send? (previous years it was 1040NR-EZ and 8843). Where can I add the 1042S form?

3) Also, I moved to US first time in august 2011, so the 6th year started in august 2016. How will it affect my forms? I am filing for 2016. Part of the year I was non-resident alien, part of it I was resident for tax purposes.

Thank you very much!
