Thanks for turning to the QuickBooks Community for support. I'd be happy to help guide you in the right direction.
If you've uploaded a Logo with the company address but would like to have it appear only once on your sales forms, you can remove it by heading to the "Gear" icon and selecting "Custom form styles" , choose the template you'd like to edit and click on "Content" then click on the "Heading" section and make your changes. Or, you can remove the logo and upload another one leaving out the duplicate information.
