Unresolved questions:
We know that “US-India Treaty (Article 21) allows F-1 students from India to claim standard deduction on 1040-NR” and “Turbotax generated Form 1040 which has to filed only by a resident (not F-1 students) allows one to take a standard deduction”.
Is there still any advantage (getting more refund etc.) that filers are taking by using TurboTax instead of simply claiming treaty exemption on a 1040NR?
