There is a tax treaty between Canada and the US as to where income is taxed. Turbotax does not handle this situation. TYou may have been doing your taxes for both countries incorrectly. I am NOT sure but I think your wages would only be taxed in the US while only the rental is taxed by both. This is because, again I'm not sure, you're deemed ONLY a resident of of the US.
if no OP provides more or different info perhaps consult with a tax pro familar with this tax treaty

Income from Real Property
1. Income derived by a resident of a Contracting State from real property (including from agriculture
or forestry) situated in the other Contracting State may be taxed in that other State. ( but I think it's also taxable in the US.
