I received an email from Turbo Tax saying that a previous employer's W2 was ready for me to import. How do I import that W2?
You must have the 2023 W-2 that you received from your employer before you can import the W-2 using TurboTax.
It's a fairly straightforward procedure, as long as you have certain information available.
See the TurboTax Help article How do I import or enter my W-2? for step-by-step guidance.
