You are being too evasive, and withholding too much information, for anyone to be able to help you with your tax filing question. If the bonus is related to a situation that you don't want to discuss in an open forum (even though you're anonymous), then you should consult a local tax professional for help.
If you want an answer to your question about the correct way to enter your 1099-NEC in TurboTax, you have to provide a lot more information so that we can understand your tax situation. A one-word or one-sentence answer is not enough. We don't care what kind of activity you are engaged in, and we don't make judgements. We just help people prepare their tax returns with TurboTax.
What is the management company? What do they manage? What is your relationship to the management company? Do you do some kind of work for them, or provide services to them, or sell something to them? Or do you have some other kind of business relationship with the management company? Do you represent or promote the management company in some way, or engage in some sort of joint activity with them? Does the management company provide some product or service that helps you make money? And of particular importance, did the management company make any other payments to you in 2023 besides the year-end bonus? If so, did they report those payments on any kind of tax form, such as a W-2 or a 1099-MISC?
