TurboTax doesn't make a solution for professional tax preparers. Please check out ProFile, our Intuit partner, for solutions for preparing and filing returns on behalf of others, via EFILE: http://profile.intuit.ca/professional-tax-software/index.jsp
TurboTax includes all the forms and schedules you need to report your self-employment income and expenses. If you're just preparing a few returns for friends and family (for free), you have a few different options.
If you choose our CD/download edition of TurboTax Home & Business, you can prepare up to 12 returns. TurboTax tailors the interview based on what you enter in the profile section of each return, so you won't be prompted to enter self-employment amounts for returns where you've answered there is no self-employment income or expenses. https://turbotax.intuit.ca/personal-tax-software/download-tax-software.jsp
Alternatively, you can go with our online editions of TurboTax and choose the edition that's best for the kind of return you're preparing. With online editions of TurboTax, you pay per return so your cost will vary based on the edition you select. https://turbotax.intuit.ca/personal-tax-software/online-tax-software.jsp
