What is a turnkey kitchen remodel?

One contract covering design, materials, every trade and the final clean, so you agree a scope and a price and then have one person to call. The alternative is managing the cabinet supplier, the plumber, the electrician, the tiler and the countertop fabricator yourself, and absorbing the cost every time one of them arrives to find the previous trade has not finished. Turnkey is not a finish level and it does not mean expensive; it describes who carries the coordination risk.
