@azadnaik thank you for your answers to my questions.
What I understand from your response is that you are either
(a) on H-1B , employed by US employer and temporarily ( short and with definite ending) working in Canada for the same employer. In such a case generally you will file your US tax return as usual i.e. world income ( including any income paid in Canada, perhaps taxed by Canada ), Married Filing Joint, child as dependent, foreign tax credit eligible for any taxes paid to Canada -- form 1666. You probably also have to file Canadian income tax -- both of these filings are supported by TurboTax
or
(b) awaiting H-1 B allocation / adjustment till early 2020 and staying / working in Canada for the same employer. In this case , above suggestions ( under para (a) ) should apply.
If the above scenarios do not apply to you , then when you leave USA soil you may be treated as a Non-Resident Alien and there may be no requirement to report any foreign income on your 2019 return { since your US sourced income stopped once you left the US soil}. Perhaps I am misunderstanding your situation -- please elucidate
Salam aliqum, Naik ji
