What TOEFL score do you need for the University of Zurich?

UZH lists "TOEFL iBT / MyBest Scores to TOEFL iBT", so MyBest scores are accepted. Results must be no more than two years old, and UZH must receive them directly from ETS using institution code 0348. Results from the TOEFL iBT Home Edition are not accepted. Applicants who need a visa must submit the certificate by the visa-applicant application deadline; others may submit it after admission, up to one week before the course starts.

For comparison, the same page asks for IELTS Academic 7 with at least 6.5 in Speaking and Writing, and does not accept IELTS Academic Online.

The page lists exemptions rather than a pathway: a UZH Bachelor's degree, or a degree taught in the relevant language from a university in a region where that is the official language, can replace a test. It also lists Cambridge C1 Advanced at grade B and C2 Proficiency as alternative certificates. The page does not mention conditional admission for English.

Requirements vary by programme and change between admissions cycles. The score that binds you is the one on your UZH programme page and in your offer letter, so check it there before you book a test.
