As a completely new user who’s self-described as “not very tech savvy”, Arch is probably a terrible idea, and you should switch distros.
I really like Debian, but something like Linux Mint or Fedora might be wiser for you; all three hold your hand more, which would be very important in your case. Fedora and Debian specifically are designed to work well with KDE, although Fedora will have newer versions.
You certainly seem willing to learn (you got through the Arch install process), and I think you still have a great opportunity to enjoy Linux, but considering you’re calling the terminal emulator “Konsole”, your self-description is probably apt. FYI Konsole is just one application to access the terminal, kind of like how Firefox and Chrome are both web browsers, but you don’t use “Chrome” to refer to web browsers.
