You file your Québec return from the same place in TurboTax as your federal return. Most TurboTax users choose to file their federal return first, but you can choose to file your Québec return first if you'd prefer.
You can submit your completed return to Revenu Québec when the NetFile Québec service is open.
Important: If your return isn't accepted by Revenu Québec when you attempt to file, TurboTax displays an error message and/or error code explaining why your return wasn't accepted. Depending on the error you receive, you may be able to resolve the error and try to submit to NetFile Québec again. You have not successfully filed until you get a Revenu Québec confirmation number.
If you're eligible to use Revenu Québec's NetFile service, continue following the steps in TurboTax until you get a NetFile Québec reference/confirmation number; it's your guarantee that your return was received. Save this number for your records.
