What should I do if an employer classified me as a 1099NEC instead of an employee? They pay with written business checks without withholds. I didn’t sign for 1099.

They didn’t give me any papers to sign to become a 1099. They also didn’t give me a w4 to sign to become a w2. But I did ask them if I was going to receive a w2 during tax time and they said yes but instead I got a 1099NEC what can I do? My employer also sent out the 1099NEC in mid February, I received his mail 2/21/2023. Do I go to H&R Block Tax? Get an attorney? If yes which attorney? Tax attorney? Employee attorney? Please help.
