Try asking again. If they say no, you'll have to wait it out. According to this post, test centers for IELTS have started to reopen (with safety precautions). So hopefully, you won't have to wait much.

Hey Natasha, Both IELTS & TOEFL scores are valid for 2 years.

Both the tests are conducted to check your English proficiency so you have to be good in the language. While both tests are acknowledged worldwide, TOEFL is usually preferred by North American universities while IELTS is preferred by European and Australian universities around the world. So we suggest that you choose your test according to the country/university/course you are applying to. Both these tests have almost similar sections. Listening, reading, speaking and writing are usually the sections of these exams. So in conclusion, both have their own difficulties so choose your test based on your preferences.
