Need to correct an credit card pmt which was entered as pd by bank but was actually paid by owner

Hi there, 

QuickBooks Online makes it easy to edit a payment and I'd be happy to show you how. 

Here's how:

1. Select Settings ⚙️.
2. Under Your Company, select Chart of Accounts.
3. Find the account associated with the payment and click Account history.
4. Select the transaction, then Edit. 
5. Find the payment .
6. In the Received From column, select the customer where the payment was received.
7. Make the correction.
8. Select Save and close, then Yes to confirm your changes.

 Give this a try and if you have other questions, I recommend contacting our support team using this link.

This is what I had tried to do.   But for some reason I had entered it under "pay down credit card" and my only choices from where the money came from are the bank accounts.

I see what you're saying. At this point I recommend you to contact our support team using this link for further assistance. One of our agents will be happy to share your screen and give you a hand.
