Hello, otcpa.
I can see the urgency of getting your migration error resolved. With this, I'll guide you with the recommended solutions to help you complete the exporting process from QuickBooks Online (QBO) to QuickBooks Desktop (QBDT).
Internal error 1009 happens when QuickBooks isn't running, no company file is open, and the connection is prevented by an open window. If you haven't performed the resolutions above, I'd recommend doing so to isolate and fix the issue. Here are the following:
- Exit and reopen QuickBooks. Then sign in to your company file.
- Make sure there are no other windows open in QuickBooks.
- Update QuickBooks Desktop to the latest release or version.
- Use the clean install process.
In case the error continues even after performing the solutions above, I'd recommend contacting our Customer Care team. They can create a case that'll trigger an investigation and get the issue fixed in no time.

Please feel free to let me know in the comments below if you have other migration concerns or questions about entering data into QBDT. I'm always ready to help. Take care, otcpa.
