Hi I filed on 1/31 and the irs still hasn't accepted my refund. I have seen people file today on a sunday and have been accepted already. Does this mean there is something wrong with my taxes

The status should update in approximately 24-48 hours but it could be longer until the IRS clears out the January backlog. If something is wrong with the return, you will get a notification that the return has been rejected. For more information on a "pending" return status, please click here. The IRS estimates that most refunds will be sent within three weeks after your e-filed returns are accepted. Many refunds will come sooner. You can check the status of your refund by going to www.irs.gov/refunds. For more information, please click here.
