I am an international student from China who came to the states in 2015. I turned into a resident alien last year (2020), so this will be my first time to file federal tax as a resident alien. I am a phd student and receive a scholarship as a graduate assistant which covers tuition and fees, insurance, and salary. So I received both W-2 and 1024-S form. The university payroll also set up my tax treaty so the first $5000 annual income was not taxed in 2020. So in my case, I don’t need to file an 8833 form anymore since the payroll did it already, am I correct? Then how should I submit my 1042-S (income code 20) in TurboTax?
