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
Many taxpayers are surprised this year because their itemized deductions are not having the same effect as they did on past tax returns. The new higher standard deduction and the elimination of certain deductions, as well as the cap on state and local taxes have had a major impact.
Your itemized deductions have to be more than your standard deduction before you will see a change in your tax owed or tax refund. The deductions you enter do not necessarily count “dollar for dollar;” many of them are subject to meeting tough thresholds—medical expenses, for example, must meet a threshold that is pretty hard to reach. The software program uses all the IRS rules that apply to the expenses you enter, and it tells you if you have enough to use your itemized deductions or if using the standard deduction is more advantageous for you. Under the new tax laws, some deductions have been capped—there is a $10,000 limit to the itemized deductions for state, local, property and sales taxes.
Your standard deduction lowers your taxable income. It is not a refund
2018 Standard Deductions:

Look at line 8 of your Form 1040 to see your standard or itemized deductions.
