I forgot my siblings on the common app? Is this a big deal?

So I am one of many children and while I listed all of them on the Questbridge application, I forgot to list all of them on the common application for my Early Action. Is that going to be a problem? I listed my oldest sister and started but then I guess I just completely forgot lol. Is this even worth sending an email about ? Should I just add it too some of the other document I am sending in?

Maybe ask your GC. If you are applying for FA, then remember to list them on the FAFSA. It will definitely work in your favor.
