Thanks for all the help here!! Really save my time!!
Sorry about the confusion, for the calendar year 2021, I was not eligible for any tax exemptions as I knew of (I didn't claim it ). And I had no income outside of the US for any part of the year (both NRA and RA time). I was on F-1 visa the whole time as a student.
For my NRA part, I only have income on W-2 (not sure how much of the amount on w-2 is from the NRA part). And for my RA part, I have stock gains and interest payment plus wages.
Thank you so much for your help.
