Don't sweat it too much, we all have made little mistakes, this isn't a huge deal. I would assume that the carboy you have is a 5 gal as others have said, which means there is very little head space. When the fermentation gets going it will likely be going over the top and clogging your airlock. Run a blow off tube to keep everything up top from getting clogged and you should be good to go!
