Ps if you want to add your spouse to your return, you can do this in the forms method. Click on the "Forms explorer" in the top blue toolbar and search for "INFO" and select "Personal information dialog". There is a box here to click to process spouse's return as well.

My spouse has been processing her own return separately.

You should be able to enter her information using the schedule 2.

Go down the list and enter info from her return there. This will include her income. 

Schedule 2 is not the appropriate way to enter this info. After much searching, I found the Pension Income Worksheet where I input the figures which has fixed SOME of the issues with the T1032.

Is there any reason you are not preparing them together?
