If the amounts are high or the adjustment cheque isn't working out, our Payroll Team can help out on their side with a payroll correction. You can contact them through the options found here: https://help.quickbooks.intuit.com/en_CA/contact.
However, this close to the form deadline, things will be pretty busy on those lines. You may find it faster to get blank forms from the CRA and Revenu Quebec and make the changes there.
Feel free to reach back out if you have more questions!
