How did I qualify for Eic with no dependants

[AamilD]

It depends on filing status.  If you have no dependents then the maximum AGI you can have if you are filing as Single/Head of Household/Widowed/Married Filing Separately is $21,430. The maximum AGI if you are filing as Married Filing Jointly is $27,380. 

If your AGI is lower then the threshold mentioned above, TurboTax will prompt you to answer some questions to see if you qualify for the Earned Income Credit.

Additionally, to enter the EIC in TurboTax, please follow the steps below:

1. Click on Tax Home from Left Side Menu
2. Click on Deductions & Credits from the main screen.
3. Scroll down till you see the section titled "You and Your Family". Expand this section and there will be an option for Earned Income Credit. Click Start next to it and answer the questions accordingly.

You no longer have to be under 65 to get the EIC if you have no children.   Just over 19.
