"the IRS says they are still processing their returns."

The IRS has released a lot of updates on this, including that the Status isn't necessary the actual status. There are people who got their refund even though the reported status is Processing.

"I suspect these returns will need to be filed again."

The point is, they Have it and they are Working on it. Why would you keep filing it again?

The IRS also mentioned not to keep filing; you're just making things worse when you keep submitting the same return over and over.
