So on Debian 10 the install did not do everything. There is a
fstrim.timer job set up for systemd, but I needed 

systemctl enable fstrim.timer

in order to activate it. 

I also made the change to my /etc/default/grub to disable 
queued trim. Thanks for the suggestions. I was feeling dumb for asking
(I am the last human being on Earth who had not moved into the 21st
century with an SSD) but I am glad I asked.
