Get your taxes done using TurboTax

I paid withholding throughout the year for all income, however I converted some IRA to a ROTH in November.   I paid the estimated tax, based on the conversion, on Jan 15.  I believe that should satisfy the pay as you go requirement.  Turbo Tax doesn't seem to agree and has reduced the amount I over-paid by a penalty, although I'm still getting a refund.  Is there a way to override the penalty in TurboTax?  I would rather the IRS asks me for the penalty, and gives me the option to plead my case.
