It is a warning advising you that you entered 2 different provinces- one where you are self-employed and another where you live. TurboTax does not support multijurisdictional returns.
Please review the provinces you have entered to see that they were entered properly.
A year later and the 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 have done everything suggested, but nothing is working. What a waste of time... :(
