After you file

First, double check to be sure the tax return was received and accepted by the tax agency:

If the tax return has been accepted, verify the federal refund status here:
www.irs.gov/refunds

 

If this site shows that the refund was approved and issued already did you choose to have any TurboTax fees deducted from your federal refund?   If so, then the refund goes to a 3rd party bank first to have the fees taken out, then the remaining refund is sent to you.    If you had the TT fees deducted and the IRS says the refund was approved and sent, try this site to see why it didn't make it to you yet.
