Where to enter spouse taxable income?
On page 1 of T1, there is a field for spouse net/taxable income. Due to space limitations, only the spouse's net income is displayed. When you click the mouse into the field or try to type a number into that field, a supporting field window will pop up, as shown in the following screenshot.
Don't forget to enter the taxable income on field 26000 as well which will be transferred to Schedule 2 automatically, e.g. Line 7

There are both spouse net income and taxable income in this window. Make sure both spouse income fields are entered, and taxable income should not be more than net income.
