Hi @JohnW222 , thanks for the reply. I read the details of the help article you linked. Item v in box 12 is not listed on my W2. However, my company provides form 3921. In the past, I've entered in all the details from my 3921 to fix the cost basis, and this has prevented the ISO sales income from double-counting. This year, after I entered the details from the 3921 to correct the cost basis, my investment income shows as $0 on the "wages and deductions" summary page, so it's back to single counting. However, on the 6251, it is still double-counted.
I'm a bit frustrated because when I call TurboTax support they tell me this is an issue that needs a CPA and I need to upgrade to TurboTax Live. However, I think it's either something I'm entering incorrectly or a bug with the product.
