How do I get Git 2.24 installed on Debian Buster?

I'm trying to get the most recent version of Git installed onto my Debian Buster machine, and I'm running into trouble. The most recent version of Git on stable is 2.20. I found that the testing branch has the right version, but I'm not having any success with backports. I've added

deb http://deb.debian.org/debian/  buster-backports main contrib
deb-src http://deb.debian.org/debian/  buster-backports main contrib

to /etc/apt/sources.list and done sudo apt-get update, but every time I run sudo apt-get -t buster-backports install git I end up with 2.20 again. I've also tried using apt-get to remove git and then install it, but no luck. Any advice? Thanks!
