You have to provide the court with information about charities you donated more than $600 to in the 2 years before filing your case. This includes money donated (either at once, or through weekly tithing or similar events) and items you donated, such as clothing donations to the Salvation Army.
Charitable organizations will provide you with receipts for tax purposes for both monetary donations and in-kind donations. You should be able to find all the information you need on that receipt. If you're tithing on a regular basis, your church may be able to provide you with a report of your donations over the last 2 years.
If you've been making regular contributions all along, you don't have to stop before filing your case. As long as the organization is considered a "qualified religious or charitable entity or organization” under the Internal Revenue Code (they'll be able to confirm that for you) and you're giving no more than 15% of your gross yearly income, the court will not ask or require the charity to return the donation.
In short, the court is interested in the details to confirm that your gifts were indeed charitable. Otherwise, anyone could open a charitable organization and receive funds from people struggling with debt to help them hide or protect the money from their creditors.
