Welcome to the Community space, @qbaccount.
Generally, once the prior payment is recorded in QuickBooks, it'll reduce the liability showing due in your account.
Since you'll need to correct the amount and remove the credit balance, I'd recommend reaching out to our Payroll Support. This way, they can make the necessary corrections by accessing your account in a secure and safe environment.
Just click this link on how to reach them: Contact Support.
Let me know if you need anything else. I'll be around to help however I can. Take care and have a good one.
