Entered wrong electronic routing number. It's for the right bank. But it's for paper and not electronic. I submitted it yesterday. How do I edit it after it's submitted ?

Did you already e-file with the wrong banking information?

Yes. Yesterday.

Can I edit the number after it's been submitted ?

If your return is rejected, you can make changes to the banking information.  If it is accepted, it is too late.  The bank will reject the refund and send it back to the IRS.  Then the IRS issues a paper check and mails it to the address on your tax return.
