The refund for one particular client is taking unusually long to process. She is claiming Head of Household with a child dependent, gets an Earned Income Credit and the Additional Child Tax Credit. The return was filed and accepted on January 28, 2019. Other clients with similar returns have already received their refunds. There are no mistakes on the return.  Is anyone else seeing this issue with IRS?  I understand that returns with the EIC etc., did not start processing until 2/15.
