Turbotax says I qualify for eitc because my total earned income is $18,248. However, my actual earned income after expenses is $19,634.92. Is this an error? How do I fix?

I am self employed and my adjusted gross income is $19,634.92. I should not qualify for Earned Income Tax credit but Turbotax is saying I do and when I click on "Why you're getting this amount" it says it's because my total earned income is $18,248. How is this calculated? Is this an error?
