How do I delete a blue pay batch amount was posted on a customer's account?

Hi there, @adventurelore.

I appreciate you for raising your concern here on the Community page. I can share with you the steps on how to handle the $945 payment transaction in QuickBooks Online.

To get started, deposit the batch payment to the Undeposited Funds. Then, match the transaction to the downloaded payment.

Here's how to match a download transaction to the manually created one:

1. Click on Transactions or Banking at the left pane.
2. Go to the Banking page, then look for the account where the payment is downloaded.
3. Tap on Find match, then Find other matches.
4. Select the payment, then hit Save.

For additional guides about managing downloaded transactions in QuickBooks Online, I recommend opening this link: Categorize and match online bank transactions in QuickBooks Online.

If you need to change or move a transaction to a different account, follow these steps to undo it. 

Please let me know how else I can help you with QuickBooks or payments. I'm more than happy to help. Have a great day!
