I'm sure it's one of the items I mentioned. Since the online version of TurboTax is not yet available you must be using the CD/download version of TurboTax. Switch to forms mode and examine the Roth IRA Contribution Limit Worksheet (likely last on the forms list or just enter Roth IRA in the Open-form form-name box). It will show why TurboTax is seeing an excess Roth IRA contribution. Examine Form 5329 Part IV to see the calculation of the excess contribution penalty.
