The efiling opened Feb 12. I don't know what they used to "submit" Jan 30, for IRS.

The IRS tells you to wait at least 21 days. That would be from the opening of filing, Feb 12. Not Jan 30.

You can go to Where's My Refund to check status. That's what the IRS has posted to do.

And the Congressional Changes are retroactive. That means things are slowed down a lot.
