W2 State Tax Section

I'm using Turbotax Deluxe desktop edition. I've just entered a W2 from an employer in Texas. I filled it out exactly as the W2 shows:

 

Box 15 State TX but Employer State ID is blank.

Box 16 State wages, tips etc has some numbers in it.

Box 17 State income tax is blank.

 

There is no state income tax in Texas. There's a note that says it can only be blank if there is no state income tax. That is all fine and dandy but Turbotax keeps flagging that W2 (need review). It also says that I can't file electronically if it's empty. What should I do?
