Dealership quoted 600 dollars for transmission drain and fill.

2023 Corolla Hatchback. I’m coming up on 60k miles so I’m looking to get my first transmission fluid change done. My local Toyota dealership told me it would be between 575 to 650 to get it done.. Seems extremely expensive to me. Is this normal or too high? What risk do I run by shopping around and getting it done somewhere else? The reason I want the dealership to do it is because I’m worried about a third party mechanic screwing something up and also not using OEM fluid.
