How do I change a donation cost value that was incorrectly entered during the Review process. I use the online version that does not have forms mode.

Here is how to edit charity donations in TurboTax Online:

Federal

Deductions & Credits

Scroll to Donations to Charity in 2018, click edit/add

Thanks but there is place to edit the donation cost value.  The only place I entered a value was during the Federal Review.  Realizing an error, I can't find any way in the Donation to Charity Interview screens to change that particular value.
