Retirement tax questions

Do you mean that you received a 1099NEC from the business where you worked as a bartender?   If you received a 1099NEC, you were not an "employee."   The "NEC" part means "non-employee compensation."  You worked as an independent contractor and are considered to be "self-employed" by the IRS.   The business where you worked issues a 1099NEC to you.
