This can be tricky, you obviously want to minimise damage, but your efforts to find the flue and vent it will be better in the long run as disused stacks should always be vented.
Firstly, if it is an open fireplace, have a good look up it from downstairs so see if you can see where the step occurs.
Alternatively you can hire a Borescope, drill 10mm diameter holes in the breat upstairs and ascertain the flue position that way.
Have fun and good luck.
