Form 4852 without prior W-2

[Proxy]

My spouse lived in the US for the entire 2023 and is a Green Card holder.

However, her employer is overseas and does not provide a W-2.

The help section in TurboTax said that to fill in Form 4852, we need a prior W-2 which my spouse never had.

How do I file the substitute Form W-2 via Turbotax Premier Online?

Thanks!

So I found that we can file W-2 using EIN as 99-9999999. The solution is in this post:
