You need to add sugar at the time of bottling to get carbonation. The 4 oz of table sugar that you added X number of days ago should be fermented out by now, and you'll need to add sugar again once you are actually bottling to ensure carbonation.
Just because you didn't SEE active fermentation when you added the 4oz of table sugar doesn't mean it didn't ferment out. 4oz is not much, and wouldn't take much for the yeast to convert.
I think you already bottled anyway, and you are going to have pretty flat beer. Should still taste pretty good, though!
