Mileage Deduction

Hello - I am a part time Lyft driver and have been since 2015. I am trying to enter my mileage as a business expense, however, after going through the various screens/questions related to mileage, I am told that I am not eligible. 

 

On the General Info page, under Expenses, I select edit for my vehicle. I enter in my car information, ownership info, personal use info, checked the box that I tracked my work miles, entered in my total miles for 2020 and my Lyft miles for 2020 (this screen shows the mileage that Lyft calculated), checked that I don't have a fleet of vehicles, and then entered 0 for other expenses. The next screen says:

"It turns out you don't get this deduction
No vehicle deduction for this Nissan Sentra"
 
I'm not sure why I am getting this message. Any help is appreciated.
