I received an Art Grant from a non-profit and it is not supposed to be taxable. They reported it on a 1099-MISC. Not sure what to do.

The Art Grant I received was reported by the non-profit charitable organization on a 1099-MISC box 7 Non-Employee Income. Per the IRS website it's not taxable:

https://www.irs.gov/charities-non-profits/private-foundations/grants-to-individuals

"Grants to individuals for travel, study, or other similar purposes (including loans made for charitable purposes, and program-related investments) are taxable expenditures, unless the following conditions are met: ... It is shown to the satisfaction of the Service that one of the following requirements is met-- ... c. The grant's purpose is to achieve a specific objective, produce a report or similar product, or improve or enhance a literary, artistic, musical, scientific, teaching, or similar capacity, skill or talent of the grantee."

What form do I file to tell the IRS it's not taxable?
