IRA Contributions

I had two employers for 2020.  The first employer was for January and February, and they had a retirement plan.  The second was for the ten remaining months of the year, and they did NOT have a retirement plan.   I contributed to an IRA, but TurboTax is claiming I don't get a tax break because I had a retirement plan through my employer.  How do I get it to recognize the second employer who did NOT have a retirement plan and hence my contributions should be deductible?
