저기요 are there multiple seasons to this series?

저기요 so I'm new to this series and the watch order i've gotten a hang of so I have a basic understanding of which 영화 to watch after ive finished this series.

But the main thing thats bugging me is that when searching 'Neon genesis evangelion' on google, it says in the episodes that there are four seasons each with 더 많이 than 10 episodes

But isn't evangelion have one season and 26 episodes? are there shorter episodes for the english version 또는 something? I'm so confused aha :c
