touchpad unexpected behavior

[Lyndie]

I just upgraded from 18.04 to 20.04 this morning.

Now, when I use the touchpad:
*To click on a window it sends it to the background instead of bringing it to the front
*To click in a text box, it pastes text that it got from who knows where instead of just providing a cursor. Each click pastes again.
*I cannot select text, it just pastes (related to the previous point)
*On the sidebar, it launches a new app instead of bringing up currently opened instances.

I checked the version of synaptic and it says everything is current.

1. Release info:
Description: Ubuntu 20.04.1 LTS
Release: 20.04

2. Package version: When I type 'apt-cache policy pkgname' it says 'Unable to locate package pkgname' and my software center has disappeared from the sidebar. When I type 'software-center' into a command line it says 'command not found'

3. I expected touchpad clicks to behave the same way they did in Ubuntu 18.04:
*Tapping in a window brings it to the front.
*Tapping into a text area brings up a cursor
*Can click and drag to highlight text for copying.
*Tapping the desktop sidebar icon shows a list of currently opened windows in that app.

4. What happens now:
*Tapping a window hides it.
*Tapping into a text box pastes text that it pulled from who knows where.
*I have trouble selecting text -- sometimes lets me, sometimes just pastes whatever text it pulled from who knows where.
*Tapping a desktop sidebar item opens a new instance of the app.

Side note: my buttons work just fine, this is only a touchpad issue.
