After you file

So I decided to help someone out since I was scared on what would happen with my refund! I put the wrong routing number so I filed Jan 31,2018 and it was suppose to go in on Feb 22, but I waited because it said on the check my refund status website to wait till Feb27 so I did. I called the bank and they verified and the refund went back to the IRS. You can call the following number to check if everything is good at 1800682745 and the extension it will ask for is 733 and I pretty much waited about 15mins and I was told to expect my refund April6,2018 through mail. Hope it helps someone!
