QB Issue Resolution:

This is how CRA says to fix a mistake.

Part way thru you will find this note

Even if your employee repays you in the same year or a different year, you still have to include the salary overpayment and the deduction withheld on the employee’s T4 slip. You cannot adjust the slip or the payroll records to reduce the total employment income or source deductions by the amount of the repayment.

After your employee has repaid the salary or wages, you can give them a letter confirming the tax year when the overpayment was included in their income, as well as the date, the reason, and the amount of repayment you received. With that letter, the employee will be able to claim a deduction on line 229 of their income tax and benefits return in the year the amount was repaid.

Hope that helps

I would simply deposit the repayment to Salaries : recovered from prior year
