If you've entered something on your return that's not covered by TurboTax Do It Yourself (Online) then you'll need to upgrade to a product that does support what you need for your return, and you'll be charged the difference. This TurboTax Canada page shows you what each version of TurboTax Do It Yourself (Online) supports: https://turbotax.intuit.ca/tax/software/online

If you upgrade the product yourself, or add something like Assist & Review or the Premium Package, those would also be additional charges.
