Texas Drivers license help

I’m 20 yrs old and I have never had a drivers permit/ learners permit. I’m taking the necessary adult 6 hour course online and when I’m done do I just schedule a driving test? I live in Texas and I’m not sure if I need a permit to take the test. I’ve read so much online that it’s getting me confused. The official website says I don’t but then says i do need one. Help please
