If you need to amend your tax return, do not file another return for that year. You must wait to receive your Notice of Assessment before making any changes to your tax return.

There are three ways to make amendments to your tax return: through CRA My Account, ReFile using your tax solution, or by mail.

For further please review the following TurboTax link,

Note: The question "Continue without changes?" may be directed at your spouse's return if you did a spousal return. In this case you would click on yes continue without changes.
