I appreciate for getting back to us as well as performing a workaround, @Ritar927.
I'll go over how we can resolve this issue so you can easily import your chart of accounts into QuickBooks Desktop (QBDT).
To begin with, you'll want to ensure you used the correct .IIF format to import your accounts successfully. Also, make certain your QBDT is up to date so that the system is running with the newest features and fixes.
After that, launch the Verify & Rebuild tool. This scans your company file for potential errors and fixes them immediately.

If this is not the case, as Fiat Lux - ASIA suggested, you can use a third-party app that allows you to import your chart of accounts. Simply navigate to the App Center QBDT and search for an app there.
You can also visit our Apps for QuickBooks Desktop page for reference.
When you're finished, you might want to look at this resource to learn more about using an.IIF file: Tasks you can do with IIF files.
I'll be available if you have any further questions about your .IIF file or QDBT. Please include any additional information in your response, and I'll get back to you as soon as possible. Keep yourself safe!
