E-filed my taxes realized I put the wrong routing number in. Federal has already been accepted what needs to be done

If you already e-filed and your return gets accepted, if the information you provided is for a closed or invalid account, the government will issue you a refund check via mail. 

If your return hasn't already posted to the IRS's system, you can ask them to stop the direct deposit. You may call them toll-free at 1-800-829-1040, Monday - Friday, 7 a.m. - 7 p.m. 

However, if your return gets rejected or you haven't filed yet, you could change your Direct Deposit information, by completing the steps below:

• Sign in to TurboTax account
• Click on Take me to my return button
• Click on the File tab 
• Click on the Start button or continue going through the screens, to edit your direct deposit information.
