I received a 1099 from my new employer. Where do I enter the information on my turbo tax?

I assume that the "1099" that you got is a Form 1099-NEC. The company that gave it to you is not your employer. You are in business for yourself, self-employed, an independent contractor. The company that gave you the 1099-NEC is your client, not your employer. You enter the income as business income in TurboTax, on the Business tab.

If you received a Form 1099-NEC from your new "employer", you are being treated as an independent contractor, not an employee.  As an independent contractor, you are self-employed.  You report self-employment income and expenses on Schedule C.  If you have expenses to report, in addition to 1099 income, and you are using TurboTax Online, you will have to use TurboTax Self-Employed.  You will also be responsible for paying self-employment tax on your net income.  For more information see the following IRS Small Business and Self-Employed Tax Center
