You're welcome, Bob218. We appreciate you for responding to this thread and providing additional details of your concern. It helps me determine and share exact information and solutions with you.

Let's make sure to change your payment notification emails from QuickBooks Payments associated with your QuickBooks Desktop. 

Since you're using QuickBooks Desktop, we can manage payment notification emails from the Merchant Service Center. Still, I recommend going to the Contact Informationsection to handle the alert setup of your emails. Here's how:

1. Sign in to the Merchant Service Center.
2. Go to the Account menu. Then, select Account Profile from the drop-down.
3. Go to the Contact Information section, and then click Edit.
4. Change the email address.

If there are other things you need to manage from there, we can consult our Payment Support Team. They can walk you through thoroughly to get everything done and change some of your details from this portal. We can view payment support contact information using this article: Contact Payments Support.
