How do I make changes to my 2017 taxes that have been printed but not mailed? I have not been able to access them again.

Unfortunately, TurboTax Online for 2017 has been discontinued, so you will not be able to access your return to make changes. However, you can still make changes using the T1-ADJ form.

Here is the link to download the T1-ADJ T1 Adjustment Request: https://www.canada.ca/en/revenue-agency/services/forms-publications/forms/t1-adj.html
