The maximum adjusted gross income and earned income for the EITC are "less than $50,162 ($55,952 if married filing jointly)" if you have 3 or more qualifying children.
The qualification for earned income tax credit (EITC) is based on your adjusted gross income (AGI) and earned income, and the number of eligible children. A good tool for understanding eligibility for EITC is the IRS guide at this link.
If you meet the qualifications and aren't receiving the credit in TurboTax, check your entries. Refer to the TurboTax article at this link for the more details on EITC eligibility.
