I am Fulltime student who have one 1099-NEC for freelance service I do. Dont really have a business. Can I not file PREMIUM? Any discounts?

You cannot use the Free Edition if you have self-employment income, because you have to prepare a Schedule C and pay self-employment tax for Social Security and Medicare.   If you would rather not pay for using online Premium, you could use any version of the desktop download ----every version of desktop can prepare a Schedule C.

Or you could try one of the free software versions:

Use this IRS site for other ways to file for free.  There are 8  free software versions available from the IRS Free File site
