The W-2 you received in 2024, is it a corrected W-2C for tax year 2022? Or is it a W-2 for 2023?
If it is a corrected 2022 W-2C then you will have to amend the 2022 tax return that you filed last year.
If it is a 2023 W-2 then you need to speak with the issuer of the W-2 to find out why you received the W-2 showing income you never received.
