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?

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.
