Hello there.

In QuickBooks Online (QBO), you can create a Bank deposit affecting Accounts Payable (A/P). Then, link the credit note.

Here's how:

1. Go to the +New button.
2. Under Other, click Bank Deposit.
3. In the Add funds to this deposit window, enter the information.
4. Hit Save and close.

After that, supplier credit and refund will linked, enabling you to match the deposit to the refund on the bank transactions page.

For more details, check this link: Handle supplier refunds and credits.

Additionally, I suggest performing a monthly account reconciliation to ensure the balances on your credit card or bank statements and QuickBooks are the same.

You might also want to consider changing your QuickBooks Community username, as it appears to contain your company ID, which may compromise your privacy and security.

Let me know if you have other questions about handling supplier credit and refund. I'm always here to help. Take care.
