I'm not sure why I typed Virginia. I was clearly deeply confused.
I found what you did when googling Elksburg Township (I'm assuming you meant Elksburg Township and not Lewis Township). And I went back and took a closer look at the tops of all the images of the pages of the Lewis County part of the Census and can find no reference to Elksburg. But that doesn't mean there isn't another element of the census that indicates Elksburg -- but it could also be a mistake at the way the data for this part of the census at ancestry.com is structured.
The fact that there is only _one_ township for all of Lewis County in the 1820 census is also interesting.
You are correct -- it is near Ohio.
