If you are not required to file a tax return because your total income is less than your filing status threshold ($12,000 for Single) then you should not file a return. You will keep the Form 1099-MISC for your records, unless an amount is entered in box 7 of the Form 1099-MISC. If the amount is $400 or more, then you are required to file a return.
TurboTaxTomK has provided various instructions on how to enter the stipend into TurboTax, in particular because you should have received a Form W-2 rather than a Form 1099-MISC.
