Hi,
I have similar scenario that I exercised the held ISO shares in 2016. I paid AMT in 2016. I sold all these shares in 2021. I followed "Guide me step by step" interview and entered all the information on form 3921. However, TurboTax did not adjust the cost basis, and this inflated my realized gain in 2021. What other steps should I do?
Thank you.
Tina
