GEP CENEX, LLC W2 information is taken, but GEP CENCAST, LLC information is not because there is no value in Box 2 of the second W2.
If TurboTax is asking to confirm that the box is blank, you can do so and TurboTax should accept the W-2 entry.
Or, just put a zero for the box 2 amount.
This does not work
You can try deleting the W-2 and then re-entering it. Don't put an amount in the box 2 entry if it is blank.
