Get copies of everywhere you applied and check the applications. 3/4ths of my apps asked a question about those sort of things, but 1/4th didn't. If NONE of your apps asked about it, then no harm, no foul - you were honest about everything they asked you in the application. If one, or more, of the schools DID ask, and you glossed over it - then you need to send an amendment to THOSE schools.
You may luck out, and even if you need to amend some, you may not need to amend the one at the school you've chosen to attend.
