TT told you to go to the processing bank's site to update the info and TT cannot tell the IRS anything any more than I could make changes to your IRS account on your behalf.
In the past the IRS was sending the refunds to the processing bank (even though they explicitly said they would not which caused a big mess ) and that bank needed updated deposit info before they had to send the money back to the IRS as undeliverable.
At no time was TT actually involved other than sending out informational emails. Please understand that TT cannot legally touch your refund money in any way at any time ... that is why there is a third party processing bank in the middle.
