It's nice to have you in the thread, @Lindainvestigator. I'd be glad to lend a hand with adjusting your payroll liability check.
If you have a credit with the agency, you'll need to enter an adjustment to correct the liability showing on your payroll liability check. To know more about liability adjustment, please refer to this article: Adjust payroll liabilities.
However, if you have penalty or additional fee with the agency, then you'll need to use the expense tab as suggested by our Community backer on this thread. I'd recommend consulting with your accountant first, to ensure an accurate record of the account/category type.
If you need additional references about payroll in the future, please feel free to access our site: Help articles for QuickBooks Desktop Payroll.
I'll be keeping an eye out for your response if you have other questions about adjusting your payroll liability check. Cheering you to continued success.
