You can list it as a charitable donation on schedule A.  The actual tax impact will depend on your tax situation.  (A deduction does not directly reduce your tax, it reduces your taxable income.)  You will need proof of what you paid, and you will need a receipt or letter from the church acknowledging your donation.  Enter it as a custom item in turbotax or itsdeductible using the actual price you paid.  (ItsDeductible works best for donations of used household items.  Specialty donations should be entered individually following the correct tax rules.)
