Taxes

I understand the implication of any delay in resolving this concern, @Jim T.

Let's isolate this concern for possible damage by running the verify and rebuild tool. This is a built-in tool that auto-detect and self-resolves any minor company file data issues. Here's how:

To Verify Data:

1. Go to the File menu.
2. Choose Utilities.
3. Select Verify Data.
   • If QuickBooks doesn't find any problems, select OK. You can keep using your company file. You don't have any data damage.

To Rebuild Data:

1. Click the File menu.
2. Go to Utilities and select Rebuild Data.
3. Hit OK to back up your company file.
4. Wait until the Rebuild is complete.
5. Click View Results.

You can repeat the same process two or three more times. Once completed, restart your device to ensure that all components are updated. You can try generating a 1099  Summary or Detail report again. 

If the issue persists, you'd want to repair QuickBooks. You can read through this article for more detailed instructions in resolving data damage on your QuickBooks Desktop company file: Fix data damage on your QuickBooks Desktop company file.

Also, you can read through these articles where you can get additional information on how to resolve unexpected behaviors when navigating around QuickBooks:
