Definitely between Turnpike Lane and Manor House, but very near the Turnpike Lane station, I would say 3-4 minutes walk from it. It is a massive residents permit zone, but the parking spaces that are near shops have pay and display, I paid a bit over £3 for about 1h15'. if you want to avoid parking on the main road, there are still a few pay and display spaces just off the main road where there are shops nearby.
Harringay council loves a ticket and has many zones

There are 2 zones in Woodgreen.
Inner Zone
Monday to Sunday: 8am to 10pm.
Outer Zone
Monday to Saturday: 8am to 6.30pm.
In direction of Green lanes (Turnpike Lane to Manor House) is mostly the outer.
pay and display, place is N22 6BP but there are more around (I know the area well)
Other options in the area are:
Morrisons (Near woodgreen tube), free parking for 2 hours and only a short bus ride to turnpike (less than 10 mins) .
Sainsburys Harringay 2.5 hours free parking and a short bus ride (10 mins).
At the side of the station is the woodgreen outer zone
