@Critter-3 - good points, the complexity of the last minute American Rescue Plan act, makes it look like Turbo Tax software missed the EITC credit when that could have only occured if the OP submitted the tax return before Turbo Tax updated the software to reflect the March, 2021 law changes......
But that is a 2020 tax return issue and not a 2021 tax return issue.
I guess it is possible for low income individuals (see the table I posted above) that failed to include their 2019 AGI, to be eligible for EITC based on their 2019 income, but that is an input error and not a Turbo Tax software calculation issue.
