We can perform some troubleshooting steps to see if data buildup on your device is preventing the Help icon from working properly in the QuickBooks Online (QBO) app, Scott.

Before we proceed, could you please confirm which application you’re referring to? Is it the QBO Desktop app or the mobile version? Any additional information you provide will help us offer a more targeted solution.

In the meantime, I recommend refreshing your device's app data to remove excessive components that might affect the program's functionality.

Here's how:

For iOS devices:

1. Go to Settings, then click General.
2. Select iPhone Storage, then tap the QuickBooks Online app.
3. Click Offload App. This will free up the storage without deleting your app's documents and data.

For Android devices:

1. Go to the Home menu or tap the three dots in the lower right corner.
2. Select Settings, then choose Refresh Data.
3. Click YES to confirm.

However, if you're referring to the QBO desktop app, you can follow the steps below to clear your QuickBooks app's cache:

1. Click the Help menu.
2. Choose Reset App Data.

If the issue persists, please ensure the app is updated to the latest version, whether on desktop or mobile. You might also want to consider uninstalling and reinstalling the app. Alternatively, you can access the Help menu by logging into your QBO account via a web browser.
