Is there a Turbo Tax glitch in Sch. C/SE reporting? It would not allow an IRA deduction.I had to override

[DavidD66]

Please clarify?  If you are self-employed you report IRA deductions (SEP, SIMPLE, or traditional) on Form 1040 Schedule 1, NOT Schedule C.  What did you override?  

You cannot e-file a tax return in TurboTax if it contains an overridden field. Overrides also void the 100% accurate calculation guarantee.

There is no glitch in TurboTax's determination of whether or not a traditional IRA contribution is deductible.

If you or your spouse is covered by a workplace retirement plan and your MAGI is above the threshold where a deduction becomes prohibited, your traditional IRA contribution is not deductible.  Keep in mind that if you contribute to a self-employed retirement plan for 2025, you are a covered individual for 2025.

Also, if you have no net profit from self-employment, you are not permitted to contribute to an IRA.  You are not permitted to deduct a contribution that you are not permitted to make.  (TurboTax would have informed you of an excess contribution, so this probably does not apply to your situation.)
