I was curious too. The FBI provides nationwide numbers for 2019: ~268k robberies, of which 16% occurred at a residence, so ~43k. [1]
The National Institute for Mental Health says that ~24k suicides are inflicted with with firearms in 2018. [2]
Hard to figure out how many robberies might have been "resolved" by an armed homeowner, but I note the FBI says that there were only 334 "Justifiable Homicides" by civilians using firearms in 2019. [3]
Thanks for looking up these numbers. I have looked in to it before, and found [0], which implies about 50,000 self-defense uses of a firearm per year. Of course, not every self-defense use involves firing a shot, and not every shot fired ends up with a death.
