Dependent

The whole reason I was filing was because my son was claimed by my mother and father and they ended up getting the two stimulus checks before this one and I got full custody of my son back he lived with me this whole year and we didn’t get his third stimulus check I didn’t go to my mom and I didn’t go to his direct express card so they told me to file my taxes again and add him as a dependent well I’m not sure if I did it right and I didn’t have no one to help me with it so my question is is did I do it right just so I can get the money for him because he has hospital bills that I have to pay because he has been sick since lastJanuary and I have been paying the bills for it and I needed that money to catch up on some of his hospital bills so my question was is did I do it right and I don’t know if I did or not thank you Jennifer Baker
