I assume you mean that you received the stipend for performing research, not for being a subject in a research study.
A stipend that you receive for doing research is supposed to be reported as wages on a W-2, not on a 1099-MISC. (And box 6 of Form 1099-MISC is for payments to a physician or other health care provider, not for people doing research.)
Ideally whoever paid the stipend to you should file a corrected 1099-MISC showing zero in box 6, and file a W-2 correctly reporting the stipend as wages. If they refuse to do that, you can report the stipend as wages that were not reported on a W-2. You will have to pay the Social Security and Medicare taxes that the employer should have withheld from the stipend. This will be the same amount that would have been withheld if the stipend had been correctly reported on a W-2.
The payments will be included in the total wages on Form 1040 line 1. On the dotted line to the left of the amount on line 1 there will be a notation "F8919" and the amount. Form 8919 will be included in your return, with reason code H in column (c). Form 8919 will calculate the Social Security and Medicare taxes. The total of these taxes will appear on Schedule 2 line 6 and will be included in your total tax liability.
Do not enter the 1099-MISC in TurboTax at all. Delete what you have already entered. Then follow these steps to enter the stipend. The first few steps might vary a bit in TurboTax Online, depending on what you have already done.
