How do I still owe and my deductions are much higher than the amount I owe

[Anonymous]

deductions don't reduce your taxes $ for $ at the highest tax brackets at the highest tax bracket about 40% at the lowest only 10% 

we can't see your returns so you may want to download  1040 instructions to see if your taxes appear correct.

look for your taxable income  starting on page 63

there could be many resons why the amount you find differs from your return.
