I am a Computer IT consultant 4 years. Just came back to being a contractor again after several years of W2. I have a TIN and a name but never did the LLC. At age 60 I am most interested in what structure will allow me to put away the most retirements money and allow me to deduct my HUGE monthly health insurance premiums.

You have a "TIN." For the acronym-averse, that a Tax Identification Number. Also known as an Employer Identification Number [EIN] or Federal Identification Number. They all refer to a business's identification number, similar to a person's social security number. [There are other purposes for an EIN.] More on tax ID numbers here EIN-employer identification # .
An LLC is a Limited Liability Company. There's a lot of info on LLCs right here business entity -- LLC. Did I say a lot? Well, yes, really a lot. Read those posts. In them you will learn that an LLC is a legal way of forming your business. An LLC does not determine tax structure as does a corporation or a partnership or a sole proprietorship.
The pension laws were changed a while back so that now a sole proprietor has more of a choice on pension structure than does an employee. For instance, you may choose a Defined Benefit pension, that will allow you to contribute enormous amounts to your pension. Example: $100,000 contribution on $350,000 net self-employed income. A more modest and more flexible plan is a UNI-k. Think of it as a one-person 401-k.
Health insurance premiums are deductible as an adjustment to income whether you are a sole-proprietor, partnership, or S-corporation. Deducting them as a C-corporation is a bit different.
Think things through carefully, and get as much accurate information as you can before you abandon the advantages of self-employment for a different structure.
