I see some invoices that have been paid to my QuickBooks. How do I know the bank where these payments went? I haven't received any payments in the bank that I had linked

Welcome to the QuickBooks Online Forum. I'll assist you with finding what bank account the invoice payments go using QuickBooks Online (QBO).

If you have manually recorded the payment transaction, you can run an Invoice and Received Payments report in QBO to view the bank account where the payment is deposited. Here are the steps:

1. From Reports, select Invoice and Received Payments. 
2. Select Custom for the Report Period and decide what date of the paid invoice you'll want to pull up. 
3. Once the list of invoices is shown, click the invoice amount.
4. In the Invoice transaction, go to the 1 payment made under the Payment Status and click the transaction date. 
5. From there, you'll see what bank account the payment goes in the Deposit to.

If you haven't received the payment manually, I would like to ask if you are using the GoCardless or PayPal to receive payments. If that's the case, you can review the bank account where GoCardless deposits the money to track where the customer payments go. Here's how:

1. In your QuickBooks, go to Apps.
2. Choose My Apps and select the GoCardless for QuickBooks or Accept Card Payments with PayPal app.
3. Select Settings then a new window will show and select Change.
4. From there, review the bank the money is deposited.

On the other hand, if you want to refund a customer who paid more than what they owe you in QBO, you can find further assistance by following this link:  Record a customer refund in QuickBooks Online.
