Question re: a small medical debt on my credit report

I was just hired to a new financial institution and have been going through the pre-start date procedure. I submitted my information for the background check which triggered me to go and look at my credit report because it had been a few months. Well when I looked at it on Credit Karma I had a small medical collection that was reported in March from a Dr appointment I had over a year ago. Long story short, I thought we paid it the night I was at the Dr, and then we moved just over a month later and they apparently had been sending bills to that address.

The collection is only 122 dollars and once I verified that it wasn't paid I called the collection company and made the payment over the phone.

My question is, will this have any effect on me getting hired? I've never had a single negative thing report to my credit history so this is bothering me quite a bit. I definitely feel as if I should call them (the company who offered me) tomorrow and let them know about it at least.
