If you are on a J-1 or F-1 visa, you will be exempt from the Substantial Presence Test for the first 2 (if non-student) or 5 (if student) calendar years that you are in the US. This means that you are considered a non-resident aliens for US tax purposes.

You will need to file a Form 1040NR to report your US source income only. TurboTax does not support Form 1040NR. You may want to try https://www.sprintax.com/ which is specifically designed to help international student nonresident aliens with their US tax returns.
