Infuriating. It would be so easy for TurboTax to have look into this and answer themselves as it's been going on for several years. In fact, they could put a message on the TurboTax screen.
In any case, I used the advice from one person which was to look at the front page of your tax filing from last year, and copy the number from there. I found an extra leading 0 had been added to my account number. I used that and it worked. This is not because my bank uses the leading 0 when they list my account. Nor, is it something I added. My guess is that the programmer decided to make account numbers the same length by right adjusting and filling in with 0s. This makes sense as some people found two 0s had been added.
