It sounds like you might have some of your income indicate in TurboTax that it is his. Review your 1099R and W2 input to insure the correct taxpayers are indicated on the correct forms. Additionally, did you indicate on both yours and his W-2s you were cover by a retirement plan at work? Review box 13 on your W2s. That would place the maximum income level for a fully deductible IRA contribution at $104,000 with complete phase out at $124,000.
