I left my company and exercised an ISO in 2016, and sold it less than a year later in 2017. Should I get a W2 for 2017?

[johnnybaja]

My previous company was acquired in 2017 and the stock account custodian sent me a 1099-B, but I haven't received a W2. TurboTax is currently showing the net gain as compensation income on line 7 of my Form 1040. Should I get a W2 for 2017, and if so, should it come from the stock account custodian or my former (now acquired) company?

The taxable amount will be taxed at ordinary income rate and will be reported on your W-2 by your former company.  

The sale will be reported on your 2017 Schedule D, Part 1 as a short-term sale without any gain or loss.

Your cost basis is the actual price paid times the number of shares, plus the compensation reported on your W-2.

Gross amounts will be the Sales price times the number of shares.
