Right before the final E-Fill for, I got ask for the Box16 value for my W-2. Why? and Box16 on Fed and State are different, what should I enter?

Do you have state income taxes withheld in box 17 of the W-2?  If not, then leave boxes 15, 16 and 17 blank (empty) on the TurboTax W-2.

if you have state income taxes, boxes 15,16 and 17 need to be completed before you e-file. Box 16 wages can differ from box 1 due to differences in state and federal laws.
