Tax Refund Status

Should I be worried?  I e-filed my return and received an Acceptance by both Federal and State on 15 March 2020.  So it is now over 4 weeks (33 days to be exact) since I efiled and have not received my Federal refund, which I authorized as a direct deposit.  I did receive my NJ State Refund.  I went to the IRS Where's My Refund Status and what I keep getting is "Your tax return is still being processed. A refund date will be provided when available".  I tried calling the phone number but due to the current situation with Stimulus and pandemic, there is no person to talk to and the recording gives the same response as website.
