How can I removed the gained from Roth IRA?

Posted at: 2014-06-09 
I have a gained of $10,000 from selling stock in my Roth IRA last year. In the form 1099-B that fidelity sent me it showed that amount. I entered those number in Turbo Tax and it said I owe around 2000 in tax. I thought gained from Roth IRA is tax free. How can I take it out? or report a gained from Roth IRA without paying tax on it?
if you withdrew the money, and are under 59 1/2 years old, you pay tax on it
