I received a CP 27 notice from the IRS notifying me that I may be eligible for the EIC. Why does Form 15112 have different questions than TurboTax to see if I qualify?

TurboTax says, "If your 2019 earned income is higher than your 2021 earned income of $_____, you could get more for the Earned Income Tax Credit (EITC)" but Form 15112 makes no mention of my income. It just asks if I'm a dependent, can be claimed by another person, etc.
