I need to file form 8843 and 1040NREZ with 1042S received. I am confused because from my school's Glacier tax system, it determined I will become resident alien since July 3 18. I received campus stipend before and after July 3. How am I gonna file this tax return? Last question: I didn't file form 8843 and 2017's 1040NREZ since 2014 because luck of this knowledge, am I able to file them through some ways? If turbotax is helpful for my case, please provide some instructions.
