That's exactly what they did. They found the error for 2021, and realized it would pancake forward into 2023, so they ask to confirm the correct 2021 carryforward loss values off your 2021 tax return (AMT Form - 6251)
Sure would have been nice if this error was announced more prominently. Without question many people will be overpaying their tax, as they'll have AMT they don't deserve, but will not check carefully to avoid this.
