Diabetes Ada 2009

Receipt for donation to the American Diabetes Association in filing tax?
I made an online donation to the Association American Diabetes during their Tour de Cure 2009 edition. I printed confirmation at the time and I still have it. Are they supposed give me a receipt for more formal filing my tax return, or is confirmed as sufficient proof? Confirmation does the date, amount, the tracking code and tax ID ADA. Thank you.
Online confirmation is sufficient to claim the amount paid as a charity Detailed deduction.
