I'm very much unsatisfied with TurboTax help phone number.  I was denied access to a representative twice.

I simply want to check the bank routing and account numbers used to efile.  

HOW CAN I SIMPLY CHECK THAT OUT????

You will need to print your return so that you can check your bank routing and account numbers. If you try to check it directly in your TurboTax account, instead of printing the return, the routing and banking numbers will show as XXXXXX.

If you're not already in your return, sign in at TurboTax.com and open or continue your return.
