If you repaid CPP Benefits it is entered in TurboTax as an "Other Deduction" and will show up on Line 232 in your tax summary.
To make this entry in TurboTax Online you must go to Deductions > Other Deductions > Other Deductions Intro and Continue from the page that appears.
You will then be prompted to "Add" an additional deduction. When the page appears that asks you to "Find", type in "misc", select Miscellaneous Deductions and hit "Go". A page will then pop up allowing you to enter your CPP Benefit Repayment.
