How do I enter the amount claimed as a charitable deduction when it is not the same as the fmv of the donated public stock due to restrictions attached to the donation?

this is from 8283 instructions (I will admit the instructions seem contradictory because there's no discussion of exactly how to enter donation of PS with restrictions). 

What’s New Section B. Under Section B, Part I, Information for Donated Property, there is a new checkbox for clothing and household items. Partial Interests and Restricted Property has been moved from Section A, Part II to Section B, Part II. Under Section B, Part IV, Declaration of Appraiser, there is a new line requiring the appraiser's name, signature, title, and date. 

You must also file Form 8283, Section B, if you gave less than an entire interest in a property or conditions were placed on the use of the property.

thus you can't use the Stock Donation Section (that's for publicly traded securities - no partial interest or restrictions)on the Charitable Organization Worksheet. use the Other Item Donation Section and select Securities not Publicly traded- this is so the donation will end up in section B of the 8283.the restriction question on the worksheet is not currently working and neither is the section that requires explanation of the restrictions.

the instructions for section B say

Exceptions. You do not need a written appraisal if the property is: 1. A qualified vehicle (including a car, boat, or airplane) if your deduction for the vehicle is limited to the gross proceeds from its sale and you obtained a contemporaneous written acknowledgment; 2. Intellectual property (as defined earlier); 3. Publicly traded securities and certain securities considered to be publicly traded (as defined in Which Sections To Complete, earlier); or 4. Inventory or property held primarily for sale to customers in the ordinary course of your trade or business.

in TurboTax you must also complete the noncash contribution worksheet

Part IX the appraisal section question is not working if the value is more than $5,000 (automatically yes)

you also have to complete part XI but that's not working in that what you enter doesn't get transferred to section B part II
