@FrankD When Canada Revenue Agency (CRA) receives your tax return, it automatically calculates any overpayment and refunds it to you. Using TurboTax to file your return, any overpayment will automatically be calculated and entered on lines 44800 for CPP and 45000 for EI of the tax return. You can see the amounts of your overpayments on these lines in the Detailed Tax Summary.
