Roth IRA

Received 1099R for Roth IRA distribution.  Distribution was within contribution amounts, account opened in 2007, I am not 59.5.  This should be a non taxable distribution, but turbo tax continues to count as taxable.  It has amount not determined checked, and code j in box 7.  What do I need to do to get this correctly entered so it will not count as taxable income?
