Inuit asks for spouses income from line 23400 but my spouses return summary only has line 15000 or 23600, so which one do I use?

[TurboTax_Susan]

Line 23400 less Line 23500 equals Line 23600. So, if your spouse didn't have any social benefit repayments, then Line 23400 is the same as Line 23600. 

You can see Line 23500 & Line 23600 on your spouse’s Detailed Tax Summary. Line 23400 is not on the Detailed Tax Summary; you will see it on your spouse’s T1.
