Get your taxes done using TurboTax

Similar issue here. I removed everything from tax return such as interest, dividends, etc except W2 and still don't get 15% or 20% for capital gain. I made a simple example $1000 gain and I am not getting either one 15% nor 20% ($150 or $200 in this case). I don't see how the explanation given by turbo tax expert make sense with this scenario. 

What is the issue here as I am under IRS max limit for max 15% rate of $434550?
