Hello there, leeann. Ensuring your employees are accurately taxed is crucial, and I'm happy to assist you in resolving any tax discrepancies on your employee paychecks within QuickBooks Online Payroll.

When there are discrepancies in the amount of taxes withheld from employees, adjustments must be made to rectify the situation. We can modify the amount from the Other Adjustment section under the Tax Withholding tab.

Following the steps below:

1. Go to the Payroll menu and select Employees.
2. Click the name of the employee, then tap the Edit button from the 

   Tax withholding tab.

3. Choose either the 2019 or earlier Form w-4 or the 2020 or later Form W-4.
4. Change the amount in the Extra Withholding field.
5. Click Save.

Once done, the adjustment will apply to your employee's next paycheck.
