Community Property Adjustments

 

Community Property Income Adjustments - both the addition and subtraction adjustments use positive numbers (assumption is the subtraction subtracts, addition adds)

 

But then the very next screen is Tax Withholding Adjustments - the addition adjustments use positive numbers, but the subtraction adjustments here use negative numbers, so on this page, the values are added for both scenarios.  This sign flip is confusing and not explained until you try to enter a value with the sign the wrong way.
