Stop Mojave updating to Catalina

I run Mojave on an iMac. I inadvertently downloaded the installer for Catalina but I do not want to upgrade. I cannot remove the installer from Launchpad. I am afraid to switch off the iMac in case it begins loading Catalina when I switch back on. What can I do?

iMac 21.5″, macOS 10.14
