No, TurboTax most certainly does prepare a Form 8949. It's done "behind the scenes" so to speak, taking information that you input using the "Stocks, Mutual Funds, Bonds, Other" interview and placing this information on Form 8949. Summary numbers off your Form(s) 8949 then flow up to Schedule D and summary numbers off Schedule D then flow up to line 13 of your Form 1040.
You problem is that you are using the WRONG basis to report the sale. Use the CORRECT basis and your "double taxation" issue goes away.
Starting in 2014 brokers were only required to report on Form 1099-B your "out of pocket" cost for receiving the stock, (which might be $0 for an RSU plan), so if you simply enter the Form 1099-B exactly as it reads you would be double taxed: you'd report the compensation on your W-2 and then also overstate your gain on Form 8949.
After entering the 1099-B exactly as it reads click the "I'll enter additional info on my own" and put the correct amount of basis in the "Corrected cost basis" box.
