Get your taxes done using TurboTax

Did you enter the 1099R for the ROTH IRA conversion?  It should be on 1040 lines 4a and 4b.  Then you added it again with the amount contributed?  How much contribution did you enter?  Even though a Roth contribution is not deductible it would give you an excess contribution error if you entered more than the max allowed.  And there would be an excess penalty on your return.
