Self employed

Thanks very much.  Another follow-up: She lives in NJ and attends college in OH.  She has one w-2 from NJ (summer income), and then she has one w-2 from OH (work study).  All of her income (w-2, interest, and stipend) does not exceed the $12,950 filing threshold.  TT shows her as owing no federal and NJ taxes and as being owed $6 in a refund from OH.  I plan to file her federal taxes based on everyone's input that the IRS will be looking for a filing based on the NEC alone.  Does the same hold true for NJ and OH?  I hate to pay the TT filing fees if she doesn't have to.  But if the states will be looking for filings based on the NEC, I guess we have no choice.  Thanks, all.
