When I filed taxes it said I wasn't eligible for the EITC for the year of 2019 even though I earned less in 2021 but I gave birth to dependent in 2021 can I still claim?

So I filed for the EITC because my income for 2021 was less than the income for 2019 but it said I don't qualify and neither does my dependent but I gave birth in 2021. After I filed taxes the IRS sent me a letter saying I was eligible for it but didn't apply but TurboTax is still telling me I'm not eligible
