Yes. Open up TurboTax and then open your tax return. Click on View > Forms. Your tax forms should now be listed on the left-hand side of the screen. You should have a Charitable Contributions Summary worksheet that shows your listed contributions or you may see your contributions listed in your forms as a Charitable Organization.
If you need to add the donations to your tax return that has been filed, you'll have to file an Amended tax return, a 1040X. You'll need to decide if adding the additional charitable donation worth filing and amended tax return, which depends on if the donation was large enough to make a difference in your tax return.
