If someone is filing a tax return for the first time you will have to send the return by mail, as the CRA usually doesn’t have the person’s complete information in their records. To print out a copy for the CRA in TurboTax CD/Download, choose “Print Return” from the “File” at the top left of the window. Click “Continue” on the “Save a copy of your return for your records”. On the “Print and Mail Your Return” page you can choose to either print the return directly, or save a PDF copy to print at a later time.

Here is where you can mail your return: https://www.canada.ca/en/revenue-agency/corporate/contact-information/where-mail-your-paper-t1-retur...
