How do you drag files or Dock Icons in Catalina?
On my old MacBook Air, I just simply click once on a file/dock icon, then hold down trackpad down for a second over the file icon, and start dragging to where I need the file to go.
For Catalina, dragging does not seem to be possible. I already tried changing the settings for the trackpad to "Tap with Three Fingers" under "Look Up & Data Detectors" feature.
