@ emmakelly30 asked: "Can i e-file as a nonresident ?"
As a nonresident of what??
Are you a nonresident of the USA? If so, what is your situation, citizenship status, etc.?
Are you a US citizen living abroad? A non-US citizen?
If you are not a US citizen and are classified as a "nonresident alien for tax purposes", TurboTax cannot prepare Form1040-NR returns, but we can tell you about an affiliate that can.
Or are you asking about a nonresident state return?
