You can get a deduction for charitable donations and state taxes paid (income or sales), but only if your total of itemized deductions is more than what your standard deduction would be.
Generally, people with few or no deductible expenses do better with the standard deduction, whereas those with lots of medical expenses, mortgage interest, casualty losses (etc.) usually benefit from the itemized deduction.
TurboTax automatically figures out which deduction works best in your favor, but you can switch to the other one.
