Hi there,
I'm James from the QuickBooks support team and I'll be more than happy to give you a hand with ordering cheques.
Based on what you've described, I recommend checking out this article which shows you a step-by-step guide on how to order cheques: Order cheques, tax forms, and other supplies. If you still need further assistance, don't hesitate to contact our support team using this link here. You can also leave a comment below with a screenshot of what you're seeing so we're on the same page.
Otherwise, enjoy the rest of your week and stay safe! :)
