If your credit card has an expiry date that has already past, you will not be able to use it to pay for your tax return. Please contact your credit card company to get a new card, or use a different card.
Alternatively, if you have an iOS or Android device, you can download the TurboTax app, login to your TurboTax account and use Apple Pay or Google Pay to pay for your return. You can find links to the mobile apps here: https://turbotax.intuit.ca/personal-tax-software/mobile-app.jsp
