So my understanding but the processing date is that today he process whatever pending action is on your account. Wether that's paying out your refund, they're clarifying certain information, or whatever. I have a few extra codes pending on mine, but I'm not sure if that's due to the fact I have to file an 8862 in conjunction with my taxes.
As for the dollar amount, someone earlier in the thread mention that. I think it's more of just a generalization, not a big deal. They use your social to look up your information your refund amount is just kind of a verification. Why it's not super accurate? No idea.
