It will not end up making a difference. The fact that you claimed your son as a dependent means he cannot get a stimulus check even if you had said he lived with you for only 7 months. Being claimed as a dependent made him ineligible to receive a stimulus check.
But how did you receive EIC for him? Did you say he is totally disabled? Did you enter his date of birth accurately?
Did he truly meet the criteria for you to claim him as a dependent?
