Have there been any updates made for you on the IRS Where's My Refund site? Once your status has been updated to approved, you should be provided with a date that you can expect your refund to be deposited into your bank account.
What is happening when Where’s My Refund? shows my refund’s status as approved?
We’ve approved your refund. We are preparing to send your refund to your bank or directly to you in the mail. This status will tell you when we will send the refund to your bank (if you selected the direct deposit option). Please wait 5 days after we’ve sent the refund to check with your bank about your refund, since banks vary in how and when they credit funds. (It could take several weeks before you receive a mailed refund check.)

If your status still shows as accepted, and it has been more than 21 days, I would call the IRS and ask if they could view your account and provide you with any updates or activity that may not be shown on the website.
