This is normal. It can take anywhere from a few days to 3 weeks to update. Until the IRS starts processing it on their own, you may not find record of it or the website may say that you have put in incorrect information when tracking your federal refund. As your return moves through the system, the status of it will be updated. Continue checking the Where’s My Federal Refund tool for updates. Updates are made daily, usually overnight.
