Since your return has already been accepted by the Canada Revenue Agency (CRA), when you receive your Notice of Assessment (NOA) (not the express) you will be able to ask the CRA or view your NOA to know what calculation was corrected. You can contact the CRA at 1-800-959-8281 once you receive your NOA to clarify if it was in fact a calculation error.
