Hi info-pmedley-ca,
Welcome to the Community. QuickBooks Online is great program that gives you the ability to print supplier cheques. I'd be glad to provide you with information on the possibility of moving the payee address on a printed cheque.
At this time, the option to move the payee address on a printed cheque isn't available. I encourage you to find a third-party app to complete the task you're looking for. You can click on the Apps tab on the left navigation menu >and then select Find Apps.
If you'd like to include the ability to move the payee address on a printed cheque in QuickBooks, I recommend that you send us Feedback by clicking on the Gear icon at the top. This is sent to our Development Team to consider for future updates.
Let me know if you have questions, I'll be happy to help.
