Hello, sbasnett.
First, make sure that your QuickBooks Desktop is updated to its latest release. This is to make sure that you have the latest features and fixes. See this update QuickBooks to the latest release article for more information.
Then, run the Verify and Rebuild Utility tool can help you fix this. The Verify Data can initially identify any data issues within your company file. Then, the Rebuild tool will self-resolve it. However, before we begin with the troubleshooting, let's secure a backup of your company file. Once done, we can proceed to verifying and rebuilding your data in QuickBooks Desktop.
Verify data:
- Go to File, then Utilities and choose Verify Data.
If it will detect an error, proceed and Rebuild your data:
- Go back to the File menu and then Utilities and select Rebuild Data.
- Choose OK if you’ll receive a message to back-up your company file.
- After creating the back-up file, the Rebuild Data utility will run automatically.
- Click OK when you get the message Rebuild has completed.
