This isn't relevant to your question - the process of finding the server
log files would be exactly the same even if you were using the "psql"
command-line tool.

This question does not make sense - if you created a database then it is
accessible.

Every commonly-used packaging of PostgreSQL includes all the
command-line tools. (Remember that pgadmin4 is a _separate project_ from
PostgreSQL itself.)

As far as I can tell, in all of this exchange you have not told us what
operating system(s) you are using, whether you're running the database
server locally or remotely, what version of what packages you installed
(and where you obtained them). How can we give you advice without
knowing any of these details?
