Hi PaulV1223,

You can reset the app data to restore it to its default settings. Let me guide you how.

1. Select Help.
2. Choose Reset App Data.

However, if you're still getting the same error, you can uninstall and reinstall the app to refresh it. Here's how:

To uninstall:

1. Drag the QuickBooks Windows app from the Applications folder to the Trash.
2. To completely remove the app, go to Finder then choose Empty Trash.

To install:

1. Select the QuickBooks.dmg file in the downloads section.
2. Drag QuickBooks to the Applications folder.
3. From the Applications folder, launch the QuickBooks App and the program will load to the sign-on page.
4. Click Sign In, if you have QuickBooks Online account.

I have this Help Articles in case you have other questions about QuickBooks Online (QBO).
