Hello there, @sinned.
Usually, this error occurs when your data is damaged or corrupted. We can try to run the Verify/Rebuild tool to identify any data issues within your company file. Then, the Rebuild tool will self-resolve it.
Here's how:
1. Go to the File menu, then hover over Utilities.
2. Select Rebuild Data.
3. On the QuickBooks Information window, select OK. Follow the onscreen steps to save a backup.
4. Let the tool repair your file.
5. When the tool finishes, select OK.
6. Go to the File menu, and then hover over Utilities.
7. Select Verify Data.
8. Let the tool check your file for data issues.
If QuickBooks doesn't find any problems, select OK. However, if QuickBooks finds an issue with your company file, click Rebuild Now.
Moreover, make sure QuickBooks has its latest release. This is to ensure that everything is up to date.
In case you'll need to record customer refunds and make deposits in QBDT, here are some articles that you can use:
• Give your customer a credit or refund in QuickBooks Desktop for Windows
• Record and make bank deposits in QuickBooks Desktop
If you happen to have further questions, please reach back out to me here. I'll make sure you're all set. Have a wonderful day!
