I don't think Cinnamon (the Mint desktop environment) has a lot of touchscreen support. You might want to consider switching to KDE or Gnome, which might be easier if you picked a different distro, such as Fedora or Ubuntu.
Might even be the perfect excuse for you to try a Universal Blue distro, such as Bluefin or Aurora. They are based on Fedora but distributed as immutable container images, meaning its really hard to bork your system. Perfect for a beginner who wants to experiment without fear of rendering their computer unusable.
