Capital Gains - Long Term ESPP

I sold some stocks that I have purchased with my ESPP - Long Term (I held them for about 10 years).  I made about 12K Capital Gains. 

I don't know if I am entering anything incorrectly as my Federal Tax Return was decreased  2,300 and my State Tax was liability increased by 500 - So the sell of these stocks are representing about 3K in taxes.

My effective tax rate is 15.18%.  I checked schedule D and they are classified Long Term.  Is there anything I need to take special attention when filling this in turbo tax?
