How do I find my 2016 AGI if I didn't file last year and was claimed by my parents?

I wrote $0 and was denied.

"If you didn't file your own return last year and you’re in TurboTax, just tell us you didn’t file last year when we ask you. But if you’ve already entered a number for your adjusted gross income (AGI), manually enter 0 instead."

This TurboTax FAQ will assist you with filing after being a dependent the previous year:
