CRA is stating that "Based on the information you gave us, we disallowed your employment insurance overpayment." How does Turbotax calculate that?

CRA website states "The CRA will refund the excess contribution to you or use it to reduce your balance owing. If the difference is $1 or less, you may not receive a refund."  However, on my NOA it is making me pay more for this overpayment issue.
