This forum is staffed by some TurboTax employees, but also by many volunteers. As you may imagine, there are thousands of questions coming in. Your patience is appreciated.
I found this TurboTax FAQ relating to your Uber discount. Though it doesn't specifically mention state returns, it does point out that you'll need to access TurboTax via your Uber dashboard.

If you find that your state return(s) aren't discounted as you believe they should be, I'd suggest contacting Uber directly. It may be that the company has changed their offer for 2018.
