I efiled a return on March 5th, received confirmation that it was accepted but when I check the "Where's My Refund" site, the status says the IRS cannot provide any information about the refund.  I have verified the social security number, the filing status and the refund amount.  There is no telephone service with the IRS currently due to Covid and I'm looking for any help regarding how I can rectify this.  This person also has not received their stimulus check.
