Deductions & credits

Hello, 
I read the responses on here (and searched endlessly online for a better explanation) and appreciate the info shared. However, could we please provide better ("real world") examples please, using more ideal figures?  

For example, if Jack received 24,500 in Social Security benefits, and his husband, Tom, received 84,000 in regular wages.  What would Jack list in the "Community Property Addition Adjustment" field, and what would he list in the "Subtraction" field? 

 

Tyvm!
