In TurboTax you enter the income as business income (self-employment income) that was not reported on a 1099-NEC. You do not have to enter any information about the company that paid you. You just enter the amount that you received.
You cannot report it as "other income." "Other income" is reported on Schedule 1 and is not subject to self-employment tax. Self-employment income is reported on Schedule C. If your self-employment income is more than $432 you will have to pay self-employment tax, even if your income is low enough that you do not have to pay any income tax. Income tax and self-employment tax are two separate taxes, but both are included on your tax return.
