That is not how I read the guidance. I am married filing jointly, the limits you listed are for a single filer with a retirement plan. I cut and pasted the paragraph below from IRS Publication 590A. Again, I think turbotax is calculating this incorrectly, but I understand that you are experts in this field and I am not. What am I missing?
Modified AGI limit for traditional IRA contributions. For 2024, if you are covered by a retirement plan at work, your deduction for contributions to a traditional IRA is reduced (phased out) if your modified AGI is:
More than $123,000 but less than $143,000 for a married couple filing a joint return or a qualifying surviving spouse,
More than $77,000 but less than $87,000 for a single individual or head of household, or
Less than $10,000 for a married individual filing a separate return.
