As far as I know, there should at least be something in your status report on the FASFA page indicating that they are processing your corrections and when you submitted them. You might try waiting a day or two and then calling them and asking them what you should do. If you don't get a good response from them, and you wait a day or two without any change in your status on the website, then I would just re-submit it again. When I submitted a correction, I don't think they ever e-mailed me about it, I think that I just went there a week later and they said that they had processed it already.
