After you file

There are many delays in refund processing due to the slow down at the IRS from the virus and launching the stimulus payments. They are apparently not taking phone calls so there is no way to call them at this time. They apparently returned to processing returns on 4/27/20 so perhaps you will see some progress soon. All you can do now is continue to track the status on the IRS web site:
