If you really fixed the problem it will take some time for the light to shut itself off. It will take several cycles of start/drive/shut down for this to happen.
You could take your car to an auto parts store and ask them to check. They will be able to see if a code has been set or if it is an old code. They should be able to clear all codes too.
Just keep in mind that if they clear all codes they will also clear the "readiness" code that most states use to pass your car for inspection. Just like the gas cap code it will take some time for the computer to sort this out too.
