I know I can edit the user crontab with:

But where is it? I don't see anything like ~/.crontab
Secondly, and more importantly, is getting a email from the user crontab. I
have in my crontab:
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=rgm
And nothing gets mailed to /var/spool/mail/rgm
ls /var/spool/mail/ -ls
total 0
0 -rw-rw----. 1 rgm mail 0 May 5 17:21 rgm
0 -rw-rw----. 1 rpc mail 0 May 5 17:07 rpc
Do I need something like postfix with a minimal installation to get the output
from my crontab?
Sorry to be "late to the party".
I did the following....
dnf install postfix
systemctl --now enable postfix
And now you are paying the memory, cpu, etc. cost of having postfix
running for something that a postprocessing MDA should/can do. Plus you
are showing that cron is not working "out of the box" as well as it
should without an MTA or a proper MDA.
My crontab....
SHELL=/bin/sh
MAILTO=egreshko
37 * * * * /home/egreshko/bin/tippy
Contents of /home/egreshko/bin/tippy
[egreshko@f31k ~]$ cat bin/tippy
#!/bin/sh
echo HI
ls /tmp
And then you can see the time has past with...
[egreshko@f31k ~]$ date
Mon 11 May 2020 11:38:01 AM CST
And this showed up in local mailbox
[egreshko@f31k ~]$ cat /var/spool/mail/egreshko

Isn't that what you wanted?
Without the fun and games of an MTA. I could easily do this. I have
done this for past installs. This time I am trying to figure this out
without the MTA bandaid; an MDA like procmail SHOULD do this right. In
fact someone did part of the job by adding the "-f cron" option to procmail.
