I've had some luck tracing underground plastic pipes by running a 125' electrician's wire snake into them and then attaching an electrician's locator to the snake. With old plastic pipes, often they are leaking and when the water is turned off mud comes in through the leak and the pipe is full of dirt. So the snake stops when it hits the dirt.
The locator I use is a cheap one I bought on Amazon for about $50. I'd give a link but I just looked and it's no longer sold. This one looks similar but I can't vouch for it:
To find the shutoff, look in the basement for a pipe that goes into the basement wall. Especially a plastic one. If you find one, and it has a shutoff inside, shut it off, take the pipe off the valve, and feed the snake into it until it hits something.
