Thanks for joining this thread, benh1.

I can show you how to disable payment options in your QuickBooks Desktop account.

It's worth noting, you can’t modify some payment methods when connected to merchant services. You can change the Payment Type to Cash if you only want to save a payment method without charging the credit card.
 

1. From the Lists ▼ menu, select Customer & Vendor Profile Lists, then select Payment Method List.
Note: Payment method should always be the same as payment type. Otherwise, you’ll receive an error when you process payments.
2. Right-click the payment method you want to edit or disable. Then, follow these steps:
       • Edit - Select Edit Payment Method. Edit the payment details, then select OK to save the changes. 
       • Disable - Select Edit Payment Method and select the Method is inactive checkbox. Then, select OK. Once inactive, the method will continue to appear in reports, but won’t be available when processing a payment.

The following article provides additional info about adding, editing, or disabling credit cards in QuickBooks.
