A charitable donation almost never changes your tax due or refund all by itself. First, your donation does not count "dollar for dollar"--it is calculated by a percentage based on your tax bracket. You need a LOT of other itemized deductions like mortgage interest or property taxes, medical expense, etc. to itemize and exceed your standard deduction.
