Once you have submitted your tax return as you did- CRA will then review your return If there is a refund of $0 showing and yet you should get a refund they will advise you when they send you your notice of assessment.
You can review line by line and compare both that were done to see if anything was missed if so you can always do an adjustment. The adjustment cannot be made until you have received your notice of assement from CRA
