Thanks. I was going off of this from the Intuit FAQ, "...or as a parent making payments on your dependent student’s loan." But I failed to note the following part, "For you, your spouse, or a person who was your dependent when you took out the loan". The important part of "when the loan was taken out."
And Intuit is quoting the specific IRS Topic on the issue at: https://www.irs.gov/taxtopics/tc456
So, as the co-signer had the Student listed as a dependent "who was your dependent when you took the loan", one can still deduct it after the student is no longer a dependent. Sorry for confusing things.
