1099 Misc for Stipend

My son received a 1099-MISC form for a stipend he received for participating in a summer fellows program through his university, which he has done the past two years and will do it one last time this summer. The intent of the stipend is to cover his living expenses while volunteering his time with an organization. When I answer the questions of whether or not he did this last year and will this next year, his tax amount owing increases and TT adds forms as if he is self-employed.  I am a little confused because I wouldn't consider this as being self-employment and taxable, but I don't know how else to report the money. Is this taxable income?  If not, how do I eliminate all the forms that are being loaded?
