If I donated more than $5000. of stock, am filing 8283, do I need to also claim the sale as income?

You would not claim as a sale unless you sold the stock first, then donated the $5000.

If you donated the stock, and then the organization sold it, you will enter in the Charitable Donations section only. It is not income to you after you donated the stock.

For my stock donations to Fidelity Charitable in Turbo Tax 2017  using form 8283, TT asks for the Date You Acquired and Cost Basis.  Why is this?  I thought my donated stock only mattered for the value and thus the acquired date and cost basis did not matter?  I thought I would avoid capital gains by this donation to Fidelity Charitable.
