Deductions & credits

@VolvoGirl   Yes. Must have earned income, but that earned income can be from 2019. 

Election to use prior-year earned income.

You can elect to use your 2019 earned income to figure your 2021 earned income credit (EIC) if your 2019 earned income is more than your 2021 earned income. To make this election, enter the amount of your 2019 earned income on Form 1040 or 1040-SR, line 27c.

 

If you test TurboTax with a taxpayer with only unemployment income in 2021 and ask for EIC the program prompts you to enter the 2019 earned income acknowledging that the 2021 amount was zero.
