No, that's not true. My Bank Routing Number is 9 digits. Make sure you're not entering the Routing Number where the Account Number goes; that field may not take 9 digits.
Try closing TurboTax, clear your Cache and Cookies and return to the File section.
Don't cut/past the Routing or Account numbers; best to type them in manually.
