1099-NEC confused

My wife is a teacher and has for the last few years done presentations and training seminars for a local university.  She is not employed by them, however, receives compensation.  In the past we have received 1099-MISC, this year its 1099-NEC.  When I enter it into the turbotax software it treats this as if she has her own business and then starts asking about the business name and address.  It also states that a schedule C form needs to be filled out.  I'm little confused as she doesn't have a business.  On top of that turbotax also advises that I cannot efile do to some of my forms.  From other posts on this site I believe it has to do with the 1099-NEC form.  Am I doing something wrong?
