I had Restricted Stock Grants vest in 2018. When that happened, Fidelity sold off a certain percentage of them to cover ~$7k worth of income taxes. A short while after that, I entered into a trade to sell the remaining stock, and got cash. My W2 clearly shows more than I earned, and I believe it includes the value of that transaction. I received a very confusing 1099-B from Fidelity that says "Short-term transactions for which basis is NOT reported to IRS...". When going through TurboTax, I added that amount ~$17k - to the 1099-B form. Now I somehow owe $7k in taxes, even though I claim 0 and single, and I have never owed before. I feel like I am doing something wrong. Does it sound right that I would end up owing that much or am I being double-taxed for something I already paid taxes on?
