Smoke on start up after oil change

Smoke on start up after oil change
So I know smoke on start up has been covered many many times on these cars but this is slightly different.
I took my car for an oil change/air filter/etc a couple days ago and unfortunately my Mechanic didn't drain all of the oil properly or he added significantly too much. Of course the car started billowing smoke as a result. I only drove the car maybe 2 km's (At first I thought maybe some oil had spilled on the headers or another area and was burning off) before draining the oil and filling it myself.
Anyway, so the car seems to be running fine and I now instead of making my own clouds as I drive I only get a nice puff of smoke on start up after the car has been sitting for a while. There is no smoke after the first 4 or 5 seconds of the car running and the car seems to need to sit for at least an hour to puff again.
My question is how long should I expect it to smoke? The oil level is correct so I assume its some sort of residual oil that's burning now. Is there anything I should do other than wait for it to stop smoking?
Before the oil change I would only get smoke on start up rarely.. Maybe once per week max. and it would be much less smoke than I get now.
All input is appreciated!
Thanks!

No experience with my Turbo in this regard but my Boxster's first AOS failure had the engine thoroughly flooded with oil.
I had the plugs changed. The SM said it could take a considerable amount of engine run time before all the residual oil was removed from the intake system. The oil in the exhaust gets burned up rather quickly.
I was away at the time so I had him drive the car and he put about 50 miles on it and when I picked up the car it no longer smoked.
More recently when the 3rd AOS failed and while the engine didn't get subjected to nearly as much oil as before in the final minute or two of running before I shut the engine off the engine was smoking to beat the band.
After picking up the car there was a bit of smoke upon engine start -- not the first start either as the engine was started at least once after the AOS was replaced to move the car from the service bay to the lot.
I think the engine smoked a tiny bit when I took off from the stop light after leaving the dealer's parking lot but it didn't smoke any more after that.
In the case of your Turbo, as long as the engine is running ok and is only smoking at start up and briefly I think all you need do is drive the car. The oil will work its way out.
What it takes is the engine should get fully up to temperature and the engine then shut off and allowed to heat soak some. Ideally before the engine cools down too much the engine should be started again and run some more so any oil that has collected as the engine sat and heat soaked will be drawn into the engine and burned.
Last but not least you need to find another place to have your car *properly* serviced.

Can you elaborate on your experience? I am having AOS & plugs replaced, then a day of testing before I pick her up. Dealer is not sure about damage to cats or other components and feels I was lucky that there wasn't substantial damage to engine. Cost is ~ $950.

I concur my 996TT smokes on startup but only after I've washed the car. So driven cold out of garage, washed and driven cold back into garage. Next morning there'll be a slight puff of smoke for a second or two then it clears.
