@Dwayne 876 , having gone through your interactions/comments with @mesquitebean , I still have one more question --- were you in the USA ( for any purpose ) during the years 2017 and 2018 or was 2019 your very first visit ?
Unless you have been in the USA at any time except for the 3 months in 2019, you appear to not have met the Substantial Presence Test and therefore would be considered a Non-Resident Alien ( NRA). Generally NRAs are taxed ONLY on their US sourced/connect income by the USA and is reported on form 1040-NR or 1040-NR-EZ. Neither of these forms are supported by TurboTax -- ( you have to use SprinTax, Tax Professional or similar services).
BTW--Are you still here ? , When did you enter the USA with the J-1 ( Trainee? / Researcher ? ) visa ?
I await your response
