(a) Do I report several stock transactions in T5008, or Schedule 3? (b) How do I get Schedule 3?

If you have received a T5008 slip, you can just enter the slip. If you didn't get a slip, you can enter your stock transactions in the Capital Gains/Losses section. Please see this TurboTax Canada FAQ for instructions: Where do I report capital gains or losses in TurboTax Online?
