[US Federal] How do I report wages for which no W-2 was required or given, especially in FreeTaxUSA?

I worked for a local jurisdiction in 2025 as a poll worker. IRS "About Form W-2, Wage and Tax Statement" says

Every employer engaged in a trade or business who pays remuneration, including noncash payments of $600 or more for the year (all amounts if any income, social security, or Medicare tax was withheld) for services performed by an employee must file a Form W-2 for each employee (even if the employee is related to the employer) from whom:

• Income, Social Security, or Medicare tax was withheld.
• Income tax would have been withheld if the employee had claimed no more than one withholding allowance or had not claimed exemption from withholding on Form W-4, Employee's Withholding Allowance Certificate.

I was an employee, not a contractor. My wages were $300. Nothing was withheld: the payroll check was (the hourly rate) x (number of hours). The jurisdiction has a policy of not sending a W-2 if the amount paid to an employee is under $600, and I got no W-2. The jurisdiction has been around long enough, and is big enough and wealthy enough, that I'm pretty confident that they know what they're doing.

If it matters or helps: I've been paying estimated taxes and I'm pretty sure that I've really overpaid there because reasons. I contributed much more than that to an HSA, and I could contribute the $300 to a traditional IRA for tax year 2025. (This was my only earned income, and I'm retired and have no retirement plan.)

How do I report my wages when I don't have a W-2?

If you know further: how do I do it in FreeTaxUSA? In the Uncommon Income / Other Income section, there's a checkbox for "Wages not on a W-2 (Form 8919)", but that form says "if you were an employee but were treated as an independent contractor by your employer", which I don't know is applicable.
