I see that you have 2 listings, @Emily-Prudence0 and neither has a security deposit.  Most minor damages that are provable to a third party can be collected through the Resolution Center with Air BNB accessing the security deposit.  
 
BTW, I was not able to see your photos for either listing for some reason.  Don't know the difference between the two listings, but you might double check your listing by a blind search so you can see what a guest sees.
 
You can get more information about Security Deposit, making a claim, using Resolution Center etc in the Help Center FAQ
 
Good luck!!
