Can I add a w2 I forgot to add my old employer just gave me it today

As your tax return has been accepted, you will need to amend your return to include the Form W-2.

Amending won't delay your original refund. However, if you are expecting a refund, we recommend that you wait to amend until after the IRS has processed your original return and you have received your refund, feel free to cash or spend it while your amendment gets processed

Please be aware that Form 1040X will not be available in TurboTax until February 23, 2023, but once it is available, you will be able to prepare and e-file your amended return.

Please see this TurboTax article for instructions on how to amend your tax return in TurboTax.
