If you took a hydrometer reading AFTER adding the priming sugar you will not get the actual FG of your beer since you added 7oz of a non-fermented sugar. The reading SHOULD have been taken BEFORE adding the priming sugar. As a result your reading will be higher than it should be.
That being said, if my information is correct and I'm calculating the correct syrup, corn syrup's gravity is 1.036 in a 5G batch so deducting that from your reading or 1.042 you would get a FG of 1.006 approximately.
I am not 100% sure, assuming this was an extract recipe, your recipe sheet should give you what the anticipated FG should be and most extract kits finish where they are supposed to be.
