As a non-resident of the U.S. you can't use any version or flavor of TurboTax to file a U.S. tax return. You are required to file IRS Form 1040NR Non-Resident return. TurboTax does not have or support that form. You will need to use the service at www.sprintax.com to complete and file the 1040NR. Any questions you may have should be asked in their support forums.
