After you file

Or if you are referring to the section in the TurboTax program for charitable donations and to Add or Edit items for valuation, that does seem to be inoperable at this time.  I will report this but since it is the weekend and with the Monday holiday it may be awhile before this is corrected.

 

You can import  from ItsDeductible from within the TurboTax program

 

To enter charitable donations -

Click on Federal
