After you file

After your tax return has been accepted, any refund will typically be issued within 21 days. 

If your tax return has been accepted and you have checked Where’s My Refund, and haven’t seen a status update, that is typical because the IRS won’t have record of the return until it is in the processing stage, so no need to worry.

If you would like to find the status of your refund you can visit the IRS website at the link https://sa.www4.irs.gov/irfof/lang/en/irfofgetstatus.jsp 

If it has been past 21 days, you can contact the IRS regarding your refund for a status update.
