If it's the same problem as mine, the summary shows it as "Deduction for CPP/QPP/PPIP (self-empl.)", but I don't think that description is correct. If you check in the detailed tax summary (Menu item: Review > Bottom Line (Tax Summary) then find a link for "Detailed Tax Summary" halfway down the page), it's actually getting that amount from line 22215: "Deduction for CPP/QPP enhanced contributions on employment income" and not the self-employed line (22210) right above it.
Revenue Agency link for line 22215
As of 2019, you can claim a deduction for the enhanced contributions on CPP and QPP pensionable earnings you contributed through your employment income.
Whether you contributed to the CPP or QPP, the maximum allowable claim is $80.85.
