Are you able to update your refund method to direct deposit at all after you’ve filed?
If you already e-filed and your return gets accepted, you can no longer change your direct deposit information. If the information you provided is for a closed or invalid account, the government will issue you a refund check via mail. However, if your return gets rejected you can update this information by opening your return and going back to the file section.
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.
