Bank Account Number

I've already filed my taxes using Turbo Tax. Unfortunately, while my bank's route number was correct, I put an incorrect bank account number.  So it took a long time for me to receive my refund.

 

I want the IRS to have my bank's correct account number.  How may I do that as there is no way to contact them at this time.  I'll need the stimulus check asap for my April rent.
