Hi, I'm on F1 OPT visa and will file Tax as a Resident Alian. I have received both W2 and 1042-S. On the 1042-S, the gross income was same as the local wage listed on my W2 from, but the income code is 19 and exemption code is Chapter 3, code 15. I found box 7 is zero, so no tax was withheld. I am not clear how to report 1042s. Many thanks!
