can you tell me what type of lawer i need for my situation with social security

As a former employee of SSA, I can understand the difficulty this causes for you.  Typically, you don't need a lawyer.  You need to bring it to SSA management's attention - repeatedly if necessary. It's not easy to "resurrect" someone after they have been erroneously put in as deceased. Even with Covid, local field offices are seeing people face to face in emergency situations, which yours would certainly seem to qualify as. They may be able to issue you an emergency payment from the local field office, which is what you should request if needed.
