Does the W2 say it is for 2022 or 2021? Were these benefits received in 2021 or 2022? If they were received in 2022, then yes, you will add them to this years tax return.
If they were received in 2021, and you did not include this income in your 2021 tax return that you filed last year you will need to Amend Your Return to include that income.
You can only report income on the return for the year it is received. You cannot combine years of income.
