I went to US in 2014 with F1 visa, and graduated in 2016. During this time, I was teaching assistant and got payroll from my school. I left US in Jan 2017, so I didn't receive my W2 form and other documents, and didn't file tax for 2016 year. I want to know, can I file tax for 2016 year to get tax return by using turbo tax with non-resident alien status? Besides, if I can, where and how can I get these documents, such as W2 and 1040S, to file tax, because I am not in US since I graduate. Thanks a lot!
