My company incorrectly reflected RRSP values on my T-4 Slip for the 2023 & 2024 tax year. Do I refile or do I do a new tax return?

Some of RRSP were double-counted by my company. I have been given amended T-4's . All I am looking for is to be advised as to doing a refile or do a whole new return?

You can only submit one tax return per tax year. 

This TurboTax Canada FAQ tells you how you can use ReFile: I've filed my tax return. Can I still make changes?

You can also make the adjustment using the Canada Revenue Agency’s (CRA) My Account service or you can print & mail a T1-ADJ T1 Adjustment Request.
