care of desert tortoise

Found this little one under my truck yesterday evening. I live in Las Vegas, NV and am pretty sure it’s a desert tortoise but this tortoise is definitely not wild. I would like confirmation on species just so I know how to properly handle it.

Hello everyone, I found a very old gopher tortoise in the middle of a dangerous intersection. I brought her home and planned to relocate, but she seems like she just doesn't feel well. Gave her water, strawberries and cukes, and that woke her up, lol. I've had her 8 hours and she hasn't moved...
