It's not W2 income. She should get a 1099NEC for it. It is self employment income.
You need to fill out schedule C for self employment business income and pay self employment tax in addition to regular income tax on it. The SE tax is to pay Social Security and Medicare tax that wasn't taken out like on a W2.
You use your own name and ssn or business name and EIN if you have one. You should say you use the Cash Accounting Method and all income is at risk. After you put in your income and expenses if your net profit is $400 or more you will pay 15.3% for 2013 Self Employment tax in addition to your regular income tax. The Schedule SE will be automatically filled out for it.
You can enter Self Employment Income into Online Deluxe but if you have any expenses you will have to upgrade to the Premium version.
