@mjunif , generally agreeing with @AmeliesUncle on the complexities involved in your filing but having a few questions for you --
(a) was this J-1 "employment at a school, public research institute or at private organization?
(b) who paid your salary -- your home country institution or the US employer ?
(c) do you have a SSN or an ITIN
(d) how many days were you present in the USA within the last two years i.e. in 2020, 2021, assuming that you were present in the USA in 2022 for only 183 days?
(e)if your employer in the USA was a private enterprise , then is there some sort of affliation with your employer in Sweden ?
I will wait for your answers and circle back when I hear from you .
Depending on your answers it may be possible for you to prepare your return using TurboTax ( or their affiliate for form 1040-NR )
