Deductions & credits

My property tax is       6,926.00

Car Registration              209.00

State Income Tax       12,046.00

SDI                                  1,885.00

Total                            $21,066.00

It seems it should just show $10,000 deduction for state, but instead it's subtracting $11,066.  Because of this it has zeroed out all of my itemized deductions and is applying the standard deduction, when my other deductions would be higher.  Look how it calculated last year.  My state taxes were higher and it used them.

Can anyone tell me why?

Thank you for any help you can offer.
