I have the same problem. I think it's related to the use of your initial. My notice of assessment for last year uses Name Initial LastName. When Turbo Tax tries to net file I don't see the middle initial. Not sure what do do or who to call.
thanks for your response. I’m not using an initial and no initial at revenue Quebec either. I called Revenu Quebec and everything is fine with them. There’s something wrong with the software program
