I've had about 15 clients get that one or the 4883C.

Most of these returns were filed on or before April 18.

Clients are having a devil of a time getting verified. The phone line is always busy. The online ID.me option (only available with the 5071C) is not user friendly, they say. Clients are spending 4 or 5 hours to get through the process. All but one of my clients who got this are over 75. One is over 100.

I had to do the verification for my tax pro account and it took me an hour.

EDIT: P.S, Not a single one of these clients requested a refund. One owed $250K. Most had small overpayments we asked to be applied to 2023. I thought the fraudulent returns were for refunds.
