TurboTax does not prepare non-resident alien returns Form 1040NR or 1040NR-EZ.
TurboTax has an affiliate partner Sprintax (one t) which can prepare those forms. You can review their website and contact them if you have any questions to see if they can prepare your return.
Here is the direct link to the TurboTax partner page at Sprintax.
