I called the IRS today 2/11. There is a delay because of the shutdown. However, you should receive your refund within the 21 days. If you filed before 1/28, your 21 days begins 1/28. Meaning your 21 day expiration will be 2/18. I filed mine 1/23 and still have not been approved. In the past, I have had my refund deposited by now. I'm in the same boat you are. Where's My Refund is updated once a day between midnight and 6:00 am.
