If you get an amended 2023 W-2 form

If you get an amended 2023 W-2 before 4/18/2023, do you not report the initial 2023 W-2, and report only the amended 2023 W-2 on your 2023 return?   Or do you report both the initial and amended 2023 W-2 on your 2023 return?

 

If you get an amended 2023 W-2 after 4/18/2023, do you amend both 2023 IRS and 2023 State return?
