What is going on when the toilette water sounds like it is still running after turning off the valve?

I presume you mean the inlet valve at the wall. Three causes:

1) tank still has water in it, so water is running down into the bowl until it drains the tank out. Look for any minor disturbance in the water in the bowl, or to be more exacct put some food coloring into the tank near the outlet flapper and see if it show up in the bowl. Sound would stop after the tank is empty, assuming the valve is actually shutting all the way off.

2) as is very common, valve seat washer has deteriorated with age and lack of use so it is letting some water in still - with the valve off (assuming nflushing does not cause a problem) flush the toilet and see if the fill valve lets water into the tank. If that is a problem, carefully disconnect the flex hose (usually better to do this at the tank than at the shutoff valve) and see if it flows - bear in mind, if the washer is totally shot or gone you will get full flow of a gallon or two per minute, so only back off the retaining nut enough to see if flowing, not all the way. If that is the case, then to work on the toilet you need to shut off the main water supply valve to the house - and if it leaks any as is usual, open a lower elevation water faucet to keep the water level below the toilet valve. And of course, consider replacing the valve (which can introduce its own problems due to wall clearance or corroded piping) so you have a shutoff valve that works.

3) what you are hearing is not actually that but a leak or running ficture elsewhere in the house
