Those items are
deductions which help to reduce your taxable income, not credits which would
reduce your taxes. For example; if your
W2 income was $9,500 it would be reduced by the $658 in deductions you have
listed, to give you adjusted gross income of $8,842. After subtracting your standard deduction and
exemption you would get your taxable income.
With a credit; if
you owe $500 in taxes and you have a tax credit such as American Opportunity
Credit for Education for $600 and you paid $2500 taxes for the year, you would
get a refund of; $2,600 which is $500 taxes owed taken from the $600 credit,
giving you a refund of $100, and as in this example, the education credit
'paid' for the taxes owed, you will also add the $2500 in taxes that was paid
to receive a refund of $2,600 in credits.
