The usual method is the '>' redirect operator, like this:
tcptraceroute ipv6.google.com 80 > /path/to/log/file
If the error message is going to STDERR (as it should be), you will need to
redirect that instead:
tcptraceroute ipv6.google.com 80 2> /path/to/log/file
To capture both, redirect STDOUT first, then set STDERR to match:
tcptraceroute ipv6.google.com 80 > /path/to/log/file 2>&1

That should only have created 1 file, empty or not.
Can you paste in the exact command you used?

Before you criticize someone, you should walk a mile in their shoes.
Then, when you do, you'll be a mile away, and you'll have their shoes.

If console redirection is not working, a possible work around is to use
the script command. This will capture everything that is sent to the
console, either via the keyboard or STDOUT/STDERR.
script /path/to/output/file
command 1
command 2
...
exit
See the man page for script.
