Please make sure that you have entered the same province both in the beginning of your return when they ask what your province of residence is and also when you enter your business information for self-employed you need to make sure you put the same province you entered as your province of residence. 

Try to log out of TurboTax and back in and then go to the "Review" section and continue to see if you are still getting the same error message. If yes then please contact our customer service for assistance.

I see you posted on March 27th.

If they have not answered you yet, I'd suggest that you send their software back and demand a refund.

That is totally unacceptable. 

You are filing in your province of "Residence", If you are working somewhere else, you have "travel expenses" in your business.
