Generally, you can only deduct charitable contributions if you itemize deductions on Schedule A (Form 1040), Itemized Deductions. For 2020 and 2021 returns, individuals who do not itemize their deductions may deduct up to $300 (or $600 if filing jointly) from their gross income for qualified cash charitable contributions to public charities, private operating foundations, and federal, state, and local governments. This does not apply to Returns from 2022 or any other year.
