I have a question, so I donated roughly 12 dollars to an overseas non-profit organization and I'm wondering if it's tax exempt or if I have to file?

Charitable donations can only be entered on Schedule A as an itemized deduction.  If your total itemized deductions are not greater than the Standard Deduction for your filing status there is no need to report the charitable donation on your tax return.

Go to this IRS website that has a search to tool to determine the eligibility of an organization to receive tax-deductible charitable contributions - https://www.irs.gov/charities-non-profits/search-for-tax-exempt-organizations

Standard deductions for 2023

Single - $13,850 add $1,850 if age 65 or older
Married Filing Separately - $13,850 add $1,500 if age 65 or older
Married Filing Jointly - $27,700 add $1,500 for each spouse age 65 or older
Head of Household - $20,800 add $1,850 if age 65 or older

To be deductible, the charity must be registered in the US as a tax-exempt organization.  There is a search tool here,

Some overseas charities have US branches, but others do not, so it depends on who you donated to.

Then, you can always list qualifying charitable donations on your tax return, but how much benefit you get depends on your other itemized deductions (mortgage interest, state and local taxes) and other filing situations that we don't know about.
