Thank you for joining the thread, @BillieJoOwen.
Since the vendor refunded you the amount, you can record a deposit in QuickBooks Online and use the payment account when sending the payment.
Here's how:
- From the New (+) icon, select Bank deposit under Other.

- Select an account where you want to deposit the amount under the Account section.

- Go to the Add funds to this deposit section, then fill the necessary information under the columns available.

- Tap on Save and close to record the transaction.
As always, feel free to read our help articles in case you need references while working with QuickBooks in the future.
Stay in touch if you have any other questions. I'm a few clicks away to help. Wishing you a good one!
