Self-Employed CPP Contributions - Are they included in Federal amount due?

I'm preparing my son's 2019 tax return using TurboTax Home & Business.  He's self-employed.

I completed the T2125 - Statement of Business Activities form, and understand that TurboTax will calculate his CPP contributions payable based on his "Net Business Income".
TurboTax shows how much taxes he has to pay as a 'Federal balance due' of $3325.00, obviously payable to CRA, which is fine.

Does the 'Federal balance due' include his CPP contribution for this year, or will he have to pay an amount to CPP separately?
