Please check your Notice of Assessment (NOA) before filing an adjustment. The Canada Revenue Agency (CRA) may have already adjusted your return for you. If they haven’t, you should make the change yourself. This TurboTax FAQ has more information on how to ReFILE your return: I've filed my tax return. Can I still make changes?
