How do I add income from a 1099-NEC that was listed in on my 2021 1099-NEC but I deferred till 2022 because I did not receive the check until Jan 2022?

You just need to report the income as Other Self-Employed Income on your Schedule C.

To do this in TurboTax Online you can follow these steps:

2. Search for self employed income (use this exact phrase, don't add a hyphen) and select the Jump to link at the top of the search results
3. Answer Yes on the Did you have any self-employment income or expenses? screen
   • If you land on the Your 2022 self-employed work summary page, select Review next to the work you're adding income for
4. Answer the questions on the following screens until you arrive at Let's enter the income for your work
5. Scroll down to the Income section and click Add income for this work
6. Choose Other self-employed income and Continue
7. Proceed with the rest of your return
