I am also confused on how to report non-statutory stock options on the 1040. I have entered the information from the 1099-B and it brought the taxpayer refund to owing.

I sold company stock. My W-2 shows Code V in box 12 for $9,429. I understand the W-2. I have the 1099-B from the brokerage firm who handled the sale and the proceed ($10,665) minus cost basis ($6,619) shows gain of $4,046.

So I included the 1099B info on Schedule D but it seems like this is reporting the gain twice?

What am I doing wrong? Plus now it shows I owe instead of refund.
