The third stimulus payment included adult dependents but not the first 2 so if you filed just to get the stimulus credit of $1800 based on you NOT being a dependent and then you amend the return to say you ARE a dependent so that your family member can now get to take the $500 other dependent credit + the EIC + the third stimulus again then that is definitely tax fraud if you do not return the $1800 + $1400 that you were not entitled to begin with.
Doing this is nothing less than "scamming" the system.
One of those "you cannot have your cake and eat it too" scenarios.
You should have discussed this with the person who normally claims you before you filed so amending would not be required.
So the bottom line is are you a dependent or not? If you are you must amend to make the return correct.
