TurboTax does nothing with that number. Box 14 is pretty much a 'memo" field where the employer informs you about various things.
Since this is appearing on a W2 it almost certainly can be read as "Disqualify Disposition" which most likely pertains to either stock acquired via an ESPP or an ISO. The number next to that notation would then indicate the amount of "compensation" - included in Box 1 - that was generated by the disqualifying disposition. This compensation figure should be added to your out of pocket basis when reporting the stock sale.
