While I was completing my return on TurboTax I ticked a box that said I would pay my taxes within 5 days. Now I want to change that but I don't see a way to do so?

As I have to print and post my return, I want to wait until I get the notification from CRA before paying. I don't know whether me ticking the "5 days" box means that I now have to pay them within 5 days.
