Having trouble paying a bounty Elite Dangerous

I did a mission on a planet to destroy some skimmers and as a result ended up with a bounty to the tune of 16k. I thought it would be a simple matter to pay the fine but the particular minor faction is only located on the planet I was on and they don't have docking requests so I can't land there. I tried going to the stations in the system but no fines are showing. The minor faction is Tollan Constitutional Party and I can't seem to find them anywhere else except for this little base/settlement which I can't land on. I've since been destroyed, thinking this would clear my bounties but all that did was make them all go dormant. Why is it in the year 2016 we can pay things off online and have places direct deposit money to our bank accounts but in the year 3302 this facility is unavailable? Surely the banking sector is not just limited to each star system in the future?

You can't pay off bounties or dormant bounties. You used to be able to, but they changed how all of that works quite a while ago.

A dormant bounty will only matter in jurisdictions controlled by that faction; if a system authority ship scans you the dormant bounty goes activate and you are wanted. Outside of their jurisdiction there's no downside. Active bounties can get bounty hunters attacking you anywhere.

If you still really want to clear that dormant bounty, switch to a sidewinder, get another player to kill warrant scan you and then kill you. You might need to do that in a system the faction is present in. Or just wait a week; after a week the dormant bounty turns to a "legacy fine" (or something like that) and you should be able to pay it off at any station in a system that faction is present in, or a factor contact in a low security system.
