If by "it" you mean TurboTax, TurboTax doesn't know and doesn't care. You simply reported a sale of "stock" that's absolutely indistinguishable from any other sale of stock that you reported. ALL sales of securities look the same on Form 8949:
Description of what was sold
Date of sale
Proceeds
Date of acquisition
Basis
What was reported on the W-2 is "compensation." The fact that some of that compensation came in the form of stock instead of cash affects absolutely nothing.
