Netfile fails when a self-employed taxpayer 65-70 who does not collect CPP elects to stop contributing to CPP. Sch8 Part 1 says you can elect to stop. How to fix?

Schedule 8 Part 1 says "However, if you were at least 65 years of age, but under 70 years of age, you can elect to stop paying CPP contributions" Turbotax Netfile fails to allow this. CRA says you must be collecting CPP, but this is not true according the Schedule 8. TurboTax Netfile review requires me to fill out a CPT30 form which is irrelevant to self-employed people.
