Thanks for your reply MinhT1. I understand that I'm an alien (not a U.S. citizen) but when I tried using Sprintax it said "Based on the information you provided, you are deemed a US resident for tax purposes, which means Sprintax software isn’t suitable for you. Sprintax facilitates non-resident tax return preparation only.
However, our partner TurboTax specializes in tax returns for US residents and you can click here to proceed.". I also chatted with Sprintax customer support and they said I would have to use TurboTax. I'm thinking it's because I have been in the US for more than 5 years
