Should I have to pay when entering a 1099-MISC tax return for a prize earning? I don't see any place to enter it.

I am not self-employed but it won't let me add my form unless it's self-employment income.

You may or may not receive a 1099-MISC reporting the income. Regardless, this is how you should enter it in TurboTax:

Click on Federal > Wages & Income [In TT Self-Employed: Personal > Personal Income].
Scroll down to the Other Common Income section and click on the Start/Update box next to Income from Form 1099-MISC.
If you previously entered a 1099-MISC. in your return, you will be brought to the 1099-MISC Summary page. Click on the Add Another 1099-MISC. box to add a new form [or Edit to change an existing form].
If you haven't already entered a 1099-MISC, answer Yes to the question Did you get a 1099-MISC? (even if you didn't get one).
On the Let's get the info from your 1099-MISC screen, complete the top part and then enter the award amount in Box 3 Other Income.
Fill out any other boxes from your paper 1099-MISC (if you have one), then click Continue.
Enter a reason for the 1099-MISC.
On the screen, Does one of these uncommon situations apply? select This was money from a lawsuit settlement and then answer the back wages question before clicking Continue.
Continue through the screens, entering the requested information.
