Accepted and being processed are two different things. Please see this article for more information.
What does "Accepted" mean?
Refund has been processed means that the IRS has approved and are ready to send you your refund.
Your return is being processed means that your tax return is being processed.
Your status should change from being processed to accepted and then a date will be given for your refund.
Keep checking the IRS website each day for that.
