thanks so much for your reply.
1. both federal tax withheld and state tax withheld on my 1042-S are 0. So I guess I do not need to report withholding tax?
2. Under the US-China article 19 treaty, a Chinese resident who goes to the US as a researcher for research will be exempt from tax for three years. My question is: since I came to US in September 2021, I am not sure if the treaty applies to me in the year 2024. Is anywhere on 1042-S indicates that I can apply treaty?
