I received a W2 after I filed my taxes, do I need to amend the W2

[adurham916]

I received a W2 from s former employer after I filed my taxes, I'm not sure what I need to do to correct it

with a new w-2 you'll need to amend that year's tax returns. with a w-2c you'll need to tell us what boxes changed because some changes do not require filing amended returns.

If the W-2 you received is "new"--meaning it was  not entered at all on your original tax return, after your original return has been fully processed, you will need to amend.

See this TurboTax support FAQ for amending a tax return - https://ttlc.intuit.com/turbotax-support/en-us/help-article/tax-return/amend-change-correct-return-a...

Do not expect quick results from amending. It can take five months or more for the IRS to process an amended return.
