Change charity Name of One Item in a donation

I donated items to multiple charities and made trips to each on several dates. TurboTax then showed a list of the dates for each charity.  I mistakenly entered one of my trips as going to Charity A instead of Charity B. Ergo, the trip shows up in the TurboTax list of trips to Charity A. How can I edit just that one trip to move it from the Charity A list to the Charity B list?
