Hello, NRUS.
Due to the user roles, you encountered an error when exporting data from QuickBooks Online to QBDT. To perform this task, you must be an administrator. I suggest verifying your user permissions for access rights.
Once verified, your user access level is administrative. Another possibility is because of the browser issue. Please log in to your QBO account using a supported web browser. For more information, please refer to this link: System requirements for QuickBooks Online, Accountant, Payroll, and QuickBooks Self-Employed.
If the issue continues, I recommend contacting our Customer Support team. They have an advanced tool to investigate further and provide the best resolution.
Let me also add this step-by-step guide on how to transfer data:
If you have any other concerns or questions, the QuickBooks Community team is always ready to help. Have a good day!
