Hello Karen, I basically understand your explanation and appreciate it. When I started jobs in 2018, I chose treaty benefit option. This why my school gave me a 1042S instead of W2. (I believe this is my mistake because I shouldn't choose treaty benefits since I became alien resident). How should I do right now? Should I continue file as non-resident with 2018 1042S or notify my school to correct my information and provide me a new W2? Best Regards!
