I was 65 last year and believe my Standard Deduction should be: standard: 15,750 add over 65 2000 add over 65 6000 23,750. The calculated deduction is 17,750.

If you look at your form 1040 then the standard deduction that you are entitled to will appear on line 12e.  It should be $15,750.  Then the enhanced deduction for seniors will appear on line 13b.  

Assuming that your income is below $75,000 then it will show $6000 on that line.  If your income is over $75,000 then the amount on line 13b will show as less than $6,000 and if your income is over $175,000 then the amount of the enhanced deduction for seniors is reduced to zero.

Your Standard Deduction on 1040 line 12e  should be 17,750 (15,750+2,000).

The new 6,000 Enhanced Senior Deduction is separate and on 1040 line 13b.  What do you have on line 13b?
