How can I delete old Gradle versions dowlnoaded by IDEA?

Hi!

I downloaded Gradle version 7.4 as instructed from the main page of it. Although everything went normal, IntelliJ did not recognize my Gradle and started downloading its own suggestion, version 7.1. I tried tweaking around a bit, deleting projects and starting new ones until something finally happened: IntelliJ decided it needed do download version 7.2, for no reason. Now I think I resolved the issue by setting up a file for the default version.

My question is, how can I delete the old versions of Gradle downloaded by IntelliJ (7.1, 7.2)? Also the program downloaded JDK 11 when I installed it, how could I remove it as well? 

Thank you!
