How do I confirm my routing and account number when entering account information to receive refund through direct deposit? It says nothing about this on the page.

In the File section of the program on Step 2 when you have a tax refund and you have selected Direct Deposit, you are specifically asked to enter your bank routing and account numbers or you are asked to verify your bank routing and account numbers that were transferred from the 2020 tax return.

Click on File on the left side of the program screen.  Click on Revisit on Step 2

It does not let me proceed to finish filing until I have actually entered and confirmed my banking information.
