I'll hear you out, saqha. I can see how hard you tried here and I understand your sentiments about this concern.
I can see that you've already been in touch with our QuickBooks chat support. Nevertheless, I advise reaching out to our customer chat support once more, as they can request account information, and this will allow them to furnish you with the validation code based on the data stored on their system.
Keep me updated in the comments if you have further questions about your validation code in QuickBooks Desktop. I'm just a reply away. Keep safe and have a good one.
