Yes, that is correct in the present tens but not in the past. The simple past tense of the verb 'to read' is 'read', although they are spelled the same they are not pronounced the same.
читать - to read /tuː ɹi:d/
Она читала - She reads /ʃiː ɹiːdz/
Она читает - She read /ʃiː rɛd/.
Something is very wrong with your answer, because it obviously has caused Duo to come up with a nonsense "correct" answer. Next time, copy/paste your entire answer here, so we can see what's wrong with it.
On the other hand (OTOH), this is a very poor exercise sentence. It should have a possessive pronoun like моя тётр or твоя тётр to make it clear whose aunt is being discussed. Тётр by itself does not translate well into English.
