The Community isn't able to provide you further details about what the charge is for since this is a public forum. Thus, I recommend contacting our QuickBooks Payments support. This way, they can check your account securely and verify the cause of the charge.
Please browse the QuickBooks Desktop with Payments section of this resource to get in touch with them. It contains the time on when they're available to assist you and how to reach them: Contact Desktop Payments support.
