In order to assist you properly, can you tell us which version of TurboTax you are using; Online or Desktop?

This calculation is automatic, made by the software, when you enter all your T4s.

If you are using TurboTax Online, you can have a look at your Detailed summary (at the top of the page) on line 44800 for CPP overpayment and on line 45000 for EI.
