Deductions & credits

I am still confused. Based on your answer it seems like it would make sense IF $13,390 was displayed in the "State and Local Income or Sales Taxes" line item two rows higher in the summary. Then $13,390 - $3,390 would net out to the $10,000 contributing to deductions if itemized, right? 

 

However on my return, the negative number in the "State and local taxes greater than $10,000" line item is much more than the "State and Local Income or Sales Taxes" line item $10,000. What am I missing?

 

Thanks!
