How do I change my bank account and routing number information ?

[Critter-3]

If you have not yet filed the return you can make the change in the FILE tab step 2.   

If the return has already been successfully efiled or mailed  it cannot be changed.

If you have filed the 2019 tax return the bank routing and account number cannot be changed.

If you have not filed the 2019 tax return the bank routing and account number are entered in the File section of the program on Step 2.
