You will need to file two returns for the 2019 tax year.
- You will need to file a Canadian return for the period you spent in Canada. You should be able to do this return at To File a Canadian Return.
- Since you are not a U.S. Citizen and have only been in the United State since August you will need to file a Non-Resident return (1040-NR).
The non-resident tax form is not supported in TurboTax. You can use Sprintax to file your Form 1040-NR.
