Point Theme – can't get rid of old advert code below post title

Hi,
I am using a child theme of the Point theme.
I previous had an adsense advert below post title when I was on v1.2.7.
I have updated to Point v2.

When I updated to Point v2 the adsense advert code for ‘below post title’ did not update to where it should appear in the theme (the box where the code would go was empty). However it must be stored in another file somewhere in the theme that I cannot see.

So if left all the advert locations empty without code (in the single post settings) – the previous adverts from v1.2.7 would still appear.

Question – how to I locate and delete this old adsense code?

Thanks R
