Did you see any pages regarding your spouse? If you select "My Info" you should see both your and your spouse's names. If you don't, then you have only prepared the return for yourself. You would need to start a new return for your spouse. 

Thank you!

I do see reference to my partner, so I guess I started a tax return for her, but I didn't notice an opportunity to enter her T4 as part of the process. I got all the way to the end of my own taxes and even NETFILE'd them assuming I'd eventually be asked for her T4, which I never saw.
