@ctrlaltdel Thanks for responding. I have downloaded this program in both Windows 10 and Linux. The Windows version works as you describe, but the Linux version does not. I am not given a choice for the program in Linux when I try to use a magnet to download. I must be missing some step to connect qBittorrent with torrent downloading in Linux when a magnet is clicked. I am still looking everywhere for a solution.
If the xdg-open box is appearing, as you said here:
I try and get a box that pops up: xdg-open
That is the box you want to click to activate and that should allow you to access your torrent app.
