This was an all extract kit. Most likely your OG reading is wrong and was probably whatever the kit listed to be. This is typical with new brewers as they do not get a thorough mix of wort and top off water and get an off reading, no worries
If it is at 9 days and has not moved past 1.020 then it's probably done. This too is a common occurrence as there are many less fermentable sugars in LME/DME and extract batches can typically stop here.
Contributing to this phenomenon is lack of starter/rehydrating yeast, underpitching, poor aeration, improper fermentation temperatures creating stressed yeast. If you take another reading in a day and it's the same, it's done.
Fermenting at 75 degrees was way too warm but moving it now won't make a difference. Because there are most likely off flavors attributed to this batch IMO you give the vessel a little shake to possibly rouse the yeast into activity and leave it be for 2 more weeks and allow the yeast to clean up some of those off flavors, then package.
