I keep getting the following when I fill out my partner's net income. How do I bypass this error when my partner's Social benefit repayment (Line 23500) is at zero?

Your spouse's net income (Line 23600) should be calculated by subtracting social benefit repayments (Line 23500) from their net income before adjustments (Line 23400).

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.
