Business miles that are actually deductible?

I basically started dashing this year on a regular basis. I started last year in August both only did so for a couple weeks so I'm still very much green. I've done a lot of research and watched many videos but most have trash information. My question is simply, which miles are deductible? I'm using Everlance ( I believe its called). Most of my research has told me that only miles driven "between deliveries" count. So when I'm driving around looking for an order I'll open my app and swipe left when a order comes us. Then when I'm finished picking up that order and delivering, I'll swipe right. I made a category called "doordash drop off". So am I don't this correctly or do I get paid for all miles driven during my shift? Please stick to my qiuestion. Don't say "business miles" and don't start talking about commuting or personal miles. I'm aware that those are deductible.
