Thanks for keeping us updated and what steps you tried so far, TopCat1.

Aside from using the Tool Hub and Verify/Rebuild Data Utility Tool, I'd like to share additional troubleshooting steps that can resolve unrecoverable errors in QuickBooks. 

Let's start by repairing the software. This process can resolve some of the most common errors when working in the software. Here's how:

1. Restart your computer. This makes sure there are no programs that may affect the repair.
2. Open the Windows Start menu, then select Control Panel.

   Note: If you're using Windows 8 or 8.1, search "Control Panel" in the Windows Start menu.

3. Select Programs and Features, then click Uninstall a Program.

   Note: If you don't see Programs and Features, select Programs instead. Then select Program and Features.

4. Click QuickBooks from the list of programs, then Uninstall/Change.
5. Select Continue, or Next.
6. Click Repair, then click Next.

   Note: The repair should start right away, but it may take a while to finish. You can leave it running, and come back once it's done.

7. Click Finish.

Once done, go back to the company file that's getting an error. Then, try to change the account of the deposit to check if you're able to save it. 

Just in case you're still getting the error, you can uninstall and reinstall QuicBooks. Here's an article as a guide: Clean Install QuickBooks Desktop.
