Can I add a w-2g from 2021 to my return for 2022, or do I need to amend last years?

a 2021 w-2g needs to be reported on your 2021 return. if not you need to amend 2021

Income has to be reported on the tax return for the tax year in which you received the income.   You are not allowed to stick 2021 income onto a 2022 tax return.   If you did not file a 2021 return you can do so by using the CD/download for 2021.   Prepare a 2021 return and mail it in.

If you already filed your 2021 return, but just left out the 2021 W-2G, then you need to amend that 2021 return after it has been fully processed in order to add the 2021 W-2G income.
