I can help you in removing the app on your device, justjed.
You can easily remove apps from your iPad. If you change your mind, you can download the apps again.
You can follow these steps:
- Touch and hold the QuickBooks app on the Home screen.
- Tap Edit Home screen.
- Hit X on the app, then tap Delete.
- Once done, swipe up from the bottom edge or press the Home button (for models with Home button).
If you want to use the app again in the future, I've added an article that will guide you in installing QBO for iPad: Download and install QuickBooks Online.
Keep posting in the Community if you need additional help in working with the program. It's always our pleasure to help.
