To help you with that specifically, I would need to know more about the entries in the Payroll Clearing Account. Generally if using Quickbooks Payroll - when the payroll is created the expense is recorded and the clearing account is credited. Then when the checks and payroll tax deposits come through checking - the checking is credited and the Payroll clearing is Debited.
It is possible that these items have not been expensed and that is why they remain in the Clearing Account - or they have not cleared the checking account yet.
