There are many questions that need to be answered before an accurate answer can be given. Income from a 1099Misc as a stipend is normally considered earned income because you are receiving money for work performed. in your case research. If the 1099 Misc is small enough you might not owe tax anyway. If there is other income besides the 1099-Misc there may income but the Credit for education expenses from 1098-T might wipe out any tax owed. There are a lot of variables to consider. Tony F CPA
You owe income tax because all money you get for almost any reason is income. You can get tax-free tuition in some cases, but money for living expenses is taxable income.
You may not owe self-employment tax. SE tax is the equivalent of social security and medicare withholding for self-employed persons. In most cases, a graduate or postdoctoral fellowship is not considered "earned income" because you are not "working", you are a student getting an education. (For tax purposes.)
Enter the 1099-MISC in the other income section of Turbotax, do not create a self-employed or small business situation. After you enter the 1099-MISC there is a page of questions, check the box for "this was a scholarship" and then check the box for "No, I did not perform a service" (you were a student getting an education). This reports your fellowship as income, you can then deduct your tuition and fees if you paid them from the fellowship.
