Do you mean the Earned Income Credit (EIC)? Just enter your income and other information in TurboTax, including dependents, then go to the EIC section of TurboTax. TurboTax will figure out whether you qualify for the credit.
To get to the EIC section, type EIC in the Search box, then click the link that says "Jump to eic."
Use the IRS EITC Assistant to see if you qualify - https://www.irs.gov/credits-deductions/individuals/earned-income-tax-credit/use-the-eitc-assistant
@heibergdee66-gma the result will be on Line 27a of Form 1040
Did you get a Form 15111 from the IRS? We're not sure why the IRS is sending them out. You might qualify for 2021 EIC based on your 2019 income instead of 2021 income.
You can look back and use your 2019 income for the EIC credit instead of 2020 & 2021. How to use the Lookback provision
