Get your taxes done using TurboTax

Not sure if I had the same problem, but I entered the wrong routing number and e-filed.  It was rejected for the bad routing number.

 

Went back to that screen and field.  When I tried to simply replace the wrong number with the right one use copy/paste, it complained about too many characters.

 

I deleted the existing routing number and was able to paste in the correct one.

 

Try deleting the existing account number and entering the replacement one.
