Do I need to enter information from T5008's and capital gains/losses if I have already entered all the amounts from T3 and T5 forms?

I have T3 slips and T5 slips and I also printed the T5008's from my CRA account as well at 2 charts from TD Waterhouse called "Realized Gains and Losses". Do I entered information from all these or will I be duplicating? Not sure if I just enter the information from the T3 and T5's or all?
