As an F-1 visa holder, you are considered as a nonresident for five years from the year you first enter the US (2013-2017). From January 1st, 2018, if you stay within the US more than 183 days, you are a resident. Therefore, you can use TurboTax to file 2018's taxes.
As far as the past three years' taxes, if you have filed a Form 1040 with TurboTax, you would need to amend your taxes to file a Form 1040NR. On Form 1040NR, you would report any of your US source income. You need to submit both the Form 1040-X and form 1040NR together:
- Download the Form 1040-X from IRS website (see below). On the front page of Form 1040-X, enter your name, current address, and social security number (SSN) or IRS individual taxpayer identification number (ITIN)
- Do not enter any other information on page 1.
- Do not complete Parts I or II on page 2 of Form 1040X.
- Enter in Part III the reason why you are filing Form 1040X.
- Complete a new or corrected form 1040-NR. As TurboTax does not support nonresident forms, click here Sprintax.
- Across the top of the 1040-NR, write “Amended”
- Attach the new or corrected return (Form 1040NR) to the back of Form 1040-X and submit to the IRS.
