When entering my Non Qualified stock options from my 1099B, I am following the Turbo tax directions of adjusting the cost basis, but the gain/loss showing is double

I enter the amount on line 12V from my W2 where instructed but the 1099B shown in turbo tax is now showing double the gain instead of making the gain equal to the proceeds

You may have entered the Form 1099-B twice somehow by mistake. I suggest you look at the forms in your program to see if there is a duplicate Form 1099-B entry and if so delete it:

Follow these instructions:

1. Choose the Tax Tools option on your left menu bar while working on your return

2. Choose Tools

3. Choose the Delete a form option under Other Helpful links 

4. Find the duplicate Form 1099-B entry in the list and delete it

Otherwise you must be entering the wrong cost basis for the sales proceeds listed on the Form 1099-B. You can determine the discount income per share of stock acquired by dividing the discount reported on your W-2 by the number of shares acquired. Add that amount to what your cost per share was and you will have the basis cost per share. Multiply that by the number of shares sold and you will have the correct cost basis to report when you enter the Form 1099-B in TurboTax.
