Just to add on to this, you can review the amount you entered on your T5 by going to the Income tab->T-Slips->T5 Investment Income.  This amounts on the summary page and in the T-Slip should reflect what you've entered.
Additionally, when you print your tax return in the File section, you can review your PDF return and verify that the amounts entered are correct.  In your case, you might be interested in Line 120 and 121 on your T1 General.
