Yes, Latin is SOV and so usually the verb tends to come at the end. But in addition to Latin having relatively flexible word order, "esse (to be)" is a stative verb and there is no object here, just a subject complement, and therefore everything is in the nominative. It is not unusual to see SVC here, Subject-Verb-Complement.
That said, "Corinna femina est" should not be wrong.
Both are fine and mean essentially the same thing. From my experience, 'est' placed between the two is the most common (at least when used as a copula).
Word order can impart some nuances, depending on the sentence; Though in this case, I'd say it's mainly down to preference.
