you select the interpreter in PyCharm independently of what the system 
thinks the default is - it's a clickable field in the bottom of the 
screen. Probably you'll be okay when you select 3.8.  If you choose to 
make a virtualenv, remember you have to install your packages in that 
virtualenv for them to be picked up - from the path you show it looks 
like you ended up with a 3.9 virtualenv. you can do that through 
pycharm, if that's what you intend to use.  they have lots of docs on that.
