Nevermind!!! I misread Turbotax. It said the capital gains tax is included in the $4.8k that I currently owe, not what my capital gains tax is total.
Your comment makes a lot of sense, and helped me understand. Turbotax does not give you all the details of the calculus because it would allow some people to use their service without paying. I did the math on my own and got a number very similar to Turbotax, so it looks good.
