I'm not an expert and it took me a while to fully get the XMLTV stuff 
and I am on Ubuntu/mythbuntu based backend. Since the backend runs a 
user 'mythtv', I'd just create /home/mythtv/ as would normally happen if 
you did an adduser command.

Once you have all the XMLTV software and prerequisites installed 
described on the wiki page (https://www.mythtv.org/wiki/XMLTV), I'd just 
switch to user mythtv with sudo su mythtv or however you do that on 
Fedora. Then run the commands as is at 
(https://www.mythtv.org/wiki/XMLTV#Setup_with_tv_grab_zz_sdjson_sqlite) 
verbatim. That will create a EPG database in the right place with the 
right permissions for user 'mythtv'. I don't use links because I don't 
fully understand them, which shows I'm not an expert. I would make sure 
you have a /home/mythtv/.xmltv/config.xml which you can link to or copy. 
On a standard Ubuntu install you don't need to.

Once you compete the setup on the wiki page, log back in a you user and 
did mythtv-setup and on Video Sources just have the source named "SD" 
that was created on the wiki page. Once setup is done and you exit you 
can start the backend.

I reboot at this time to make sure things work automatically.  I find 
that mythfilldatabase usually runs on reboot. It it doesn't, just login 
as user 'mythtv' and run mythfilldatabase.
