The IRS refund processing doesn't happen in one fell swoop ... it is a pipeline where you could be stopped more than once and delayed each time. The is another NOT NORMAL year for the IRS so millions of returns have been delayed for many reasons. All you can to is wait patiently and check the IRS site every few days for a progress update : www.IRS.gov/refund
Please see What if my IRS refund is taking longer than 21 days? for information what to do and why it might take longer.
