Whoa! 1,400 is not the EIC. That is the 3rd Stimulus payment. You will get that if you are not a dependent. That is the Recovery Rebate Credit on line 30.
If you were a dependent on a 2020 return but filing independent for 2021 you can get it now and they don't have to pay it back. So say NO you did not get one because you didn't one, your parents got it.
The 3rd Stimulus payment is really based on 2021. The IRS just sent the checks out using 2020 to get them out fast.
