I prepaid my 10% early withdrawl fee on a 401k distribution, but the turbotax system is assessing an additional fee, how do I fix this?

I received a 1099-R for an early 401K withdrawal.  I prepaid the federal tax and early withdrawal penalty of 10% at the time of withdrawal.  TurboTax is assessing another 10% early withdrawal fee in the calculation of my refund.  How do I get the turbotax system to accurately reflect that the fee has been paid.
