DTC Fee for Donation of Appreciated Stock

[NY taxpayer]

Where do I include the cost of a DTC (transfer) fee that it costs me to donate appreciated stock to a charity.  This is a fee charged to me by the brokerage firm that held the stock I am transferring.

I believe this is deductible.  (E.g., if mileage to make a deduction is deductible, presumably, fees I have to pay to do so should likewise be deductible.)  But I can't figure out where in the Turbotax data entry fields I should put this.  The only "expense" category for stock donation is travel expense.

That fee is not deductible.
