TurboTax Online will automatically generate a Schedule 7 if the information you enter into your return indicates that you need one, like Home Buyers' Plan (HBP) repayments. You can enter this information by selecting RRSPs then RRSP Profile from the left side menu.
You can view your Schedule 7 by saving or printing the PDF Archive of your return. Please see this TurboTax FAQ for instructions: In the online edition of TurboTax, how do I print a copy of my tax return?
