This is a source of frustration for many people, and I don’t know exactly why they do it, but what they say is that Its Deductible prices during the year are estimates, and they are converted to their final values when you import the donations into TurboTax.
Regardless of the values that the program gives you, you are responsible for making sure that the donation values are actually reasonable for the items that you donated in the condition that you donated them in the retail market and part of the country where you live. If the IRS audit you, you will have to offer of proof that the donation values are reasonable, and some auditors have not accepted Its Deductible values. If you think that any values are not reasonable for your part of the country or your items, you can delete the donations and then re-enter them using a custom value.
