Recently discovered an error in my tax return for 2023. It appears that I failed to include my home office expenses for the year 2022, resulting in an overpayment of $3800 to the Canada Revenue Agency. Is there a process available to rectify this oversight and potentially recover the overpaid amount? I had a T4044 form for 2023 but did not receive one for 2022. Can I request this form from my HR department for the 2022 tax year?
