I am a Chinese citizen, and a student here and a Residential alien for 2020 tax year. I am eligible for the tax treaty article 20(c), where $5000 of the income is exempt from federal tax. On my W2, it reflected this treaty: box1 (federal income) is $5000 less than box 16 (state income).
I filed my tax returns via turbotax days ago, and turbotax didn't ask for 1042S. I just filed and all the tax returns have been approved.
Today, I found out I did received 1042S. Should I amend the tax returns? If so, how?
