Tried Migration Assistant?:

If you have any Time Machine Backup(s), of this Mac, from prior to all of this, then you could find out what you have by using Migration Assistant.  So, use migration assistant. Does anything come up?

If you never made a backup, then no, it will not find any.

To get Mojave, what you could do is reinstall it all through a USB Bootable Installer for Mojave, and then finally, reinstall it all it. Note down the applications you had installed, and contact the developer, requesting new installation files.

You need a backup you did before you installed Catalina. If you are trying to use one done now with Catalina, it is in progress and you cannot use it until it is finished - is that the first backup you ever did? If so, it will take quite some time before it is finished.

If you do not have a backup, then it is next to impossible. Since your machine can run Catalina, it will not offer you to install Mojave as that is only possible with a functioning backup of the older OS. You will need to re-download your apps from the app store, there are no "installation files".

If you erase, and then (while still in recovery) choose to reinstall, you should be getting Catalina to download. No idea what you mean with finishing a bacup - you can do one once you have erased and reinstalled the OS. But that will not get you an older backup - only a brand new one. A backup consists only of what is on the computer at the exact time you are making it.

Sorry, I still have no idea what that is. Are you referring to the app installer? You'd get that at the app store (as long as the app is available there). On Macs an installer contains all the files necessary for the app to function.
