Hi, I sold stock options on Fidelity. The taxes have been withdrawn right away. My income/gain from that sale is now in my W-2. That means I paid taxes for that income. Fidelity sent me the form 1099-B with exactly the same gain as in my W-2. But 1099-B doesn't mention any taxes which I paid (0.00 for Federal and State). That's why I need to pay the taxes again.
I found the thread on this forum which is very similar to my case: https://ttlc.intuit.com/community/taxes/discussion/1099-b-doesn-t-show-withholdings/00/2505900
But it's not clear what I should do in the TurboTax to avoid a double taxation. What does it mean 'adjust the cost basis'? Is it allowed to change the data in the 1099-B form? Fidelity sent to IRS one data and I'll send completely different data.
Thanks in advance!
