How stupit it is,help me!!!

I made a mistake in my son's application fee for I-485, I overpayed $100.00. Who can tell me that the USCIS will reject the case or ask me to re-send a correct amount check?. I sent the applications several days ago, I did received the receiption from USCIS.

The busier, the more mess.

I hope the god bless my family.
