Are you claiming the foreign earned income exclusion or the foreign tax credit?
Do you have three sources of income? You mentioned a W-2, a T4, and self-employment. Where do you actually do the work for each source of income? A W-2 could be foreign income if you work outside the U.S. for a U.S. company. Do you do the work for the Canadian employer in Canada or in the U.S.? Where do you do the self-employment work ("side hustle")?
Where exactly do you see that TurboTax is assuming that all of your income is foreign income?
Are you using TurboTax Online or the desktop TurboTax software installed on your computer? Which edition are you using (Basic, Deluxe, Premier, etc.)?
