That means that the IRS has received your tax return and it is being processed. After this the IRS will go from processing your tax return to approved or accepted. Once accepted, your tax refund will be on its way to you. It takes approximately 21 days to see it in your account if you chose the direct deposit option and 6 weeks if you ask for your check to be mailed to you. You can track the status of your refund with "Where's My Refund" tool. Use this link to do so.
