The IRS closed their processing centers in late March because of the Covid-19 pandemic. Anything you mailed to them is sitting in one of the large trailers full of unopened mail that are parked outside the IRS processing centers. An IRS spokesperson recently said that they have about 11 million pieces of unopened mail. They are just now starting to reopen the processing centers, but they have limited staff and a huge backlog, so it will be quite a while before your tax return is processed or any status information is available.
