Traditional IRA deduction

After inputting my husband's IRA contribution, TurboTax indicated that he could not deduct the contribution because his MAGI was over $123,000 while being covered by a retirement plan at work.  He is not covered by a retirement plan at work.  He changed jobs in March to a job that did not have any retirement plan.  Shouldn't he be allowed to contribute based on the income earned at the new job that did not have a retirement plan?
