how to fix payroll liability error qb desktop

I use a payroll service and then manually enter payroll in qb. The payroll service credited an employee's LST tax instead of debited it. Need help with how to enter. I've made an LST adjustment payroll item. Employee's gross and net are correct when looking at the paycheck. But when I go to the total for all employees the gross wage is more and so is employee taxes. Not sure how to correct and help would be much appreciated!!
