Just coming back to support what others are reporting now. This same client went back in this morning and completed the process of entering their bank account information. They first entered the '0" and didn't check either button. That did not work. Then they chose the "Refund" button and entered "0" as the amount. It worked fine.
One thing I will mention for clients who aren't able to get past the first screen. The abbreviations for "Street", "Circle", "Boulevard", "Drive" , etc must conform to the USPS guidelines. That's true even if the original return used them incorrectly. So anyone who keeps failing the initial screen should jump over to the USPS Zip code lookup and verify that the address they are entering conforms to those guidelines.
