There is nothing Turbo Tax can do. Once you submit your return, you have to wait on the IRS to process them.
It can take anywhere from a few days to 3 weeks to update and show the status. The 21 days is just an estimated time frame. The IRS began processing returns on 2/12, you may not find a 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.
Since Turbo Tax will not have the status of your refund, continue checking the Where’s My Federal Refund tool for updates. Updates are made daily, usually overnight.
