We appreciate you providing the error you received, Abhood2.
Usually, this error occurs due to incorrect mapping or formatting. Hence, I recommend reviewing your CSV file to ensure it follows the format accepted by QuickBooks.
You can create a 3-column or 4-column format with the help of this article: Prepare your CSV file for bank upload to QuickBooks.
If the file details and format are correct but the issue continues, try logging out and then logging back into your account before importing your CSV file again.
