I am a Chinese and I know I qualify for the US-China treaty for J1 visa holder. But I do not see any where asking about nationality or determine the treaty. Is it normal?

I am a postdoc researcher at a US university. I was determined by Sprintax that I am a resident alien. I did my master in the US and had filed tax return back then. I came back to US in September 2015 as a postdoc researcher with a J1 visa. During 2016, I was paid by Swiss fellowship for salary. I received 200 dollars for helping in teaching in the US university. But I did not put in my salary from Switzerland. Is this normal? Do you not need this information for tax return? Thanks
