Same errors are coming up fro me as well. No matter what I do, it keeps giving me the same error message. TurboTax keeps toggling me on to "self-employed". I am NOT self-employed and I didn't click anything that would give TurboTax the idea that I was. I have done everything suggested, but nothing is working. What a waste of time... :(
Your province of self-employment is different from your province of residence. TTO does not support Multijurisdictional returns. Review your entries.
