I work as a contractor for the United Nations. They simply deposit money into my account. No tax info. Where should I add this income?

You would enter this income as self employment income iin TurboTax.  As a US citizen working as a contractor for the UN without a 1099-NEC, you should report this income in TurboTax as Self-Employment Income (Schedule C). You must pay self-employment tax (social security/medicare) and income tax, as the UN does not withhold these taxes.

If you are using TurboTax Online you should use TurboTax Premium (formerly Self-Employed) . It was designed to handle Schedule C for self-employment income and expenses. While Deluxe may allow entering simple 1099-NEC income, Premium is required to properly calculate, deduct expenses, and file Schedule C.

All TurboTax Desktop (CD/Download) products—including Deluxe, Premier, and Home & Business will support Schedule C for reporting self-employment income and expenses. TurboTax Home & Business has the best guided experience for business income. 

You will be able to enter any ordinary and necessary business expenses to reduce your self-employed income. TurboTax will guide you.

You can enter this self-employment income as follows:

1. Click on Search at the top right of your TurboTax screen
2. Type schedule c in the search box
3. Click on the link Jump to schedule c
4. Your screen will say Did you have any income and expenses for a business in 2025? Answer Yes
5. Follow the TurboTax screens to enter your self-employment income and business expenses
6. Make sure to answer all follow-up questions to properly complete your entry
