I NEED TO CHANGE MY BANK ACCOUNT NUMBER AND NO ONE AT TURBO TAX KNOWS HOW TO DO THAT?

See this FAQ: How do I change my transferred direct deposit information?

I was having the same issue.  I found that if I went forward from the page that would only show my bank account numbers, I would be taken to the next page where I can revisit my account information.  I was able to make the bank account changes there and continue to file.
