那里找他们呢？网上能找到吗？

If you made donations, you will need to use itemized deduction to reflect such donations in Schedule A. The place you made donation to will give you a receipt, you will have to make an estimation for the stuff you have donated. Make sure you deduction the fair market value at the time you gave them. If the amount of your deductions is more than $500, you must complete and attach Form 8283.

要claim charity deduction，必须使用itemized deduction。简单地说就是如果你没有买房子的话就不用考虑charity deduction了。因为一般只有买了房子以后，itemized deduction才会比standard deduction高。一般yellow page上面都会有的。找一下charity就可以了。

也想知道，但是估计没有几个钱。
