if I'm filing social security payments only (I'm retired), what employment category do I use?

is retirement payment considered unemployment income?

No, your Social Security income is not considered to be unemployment.  

There is a separate category within TurboTax to enter Social Security income.  Look for Retirement Plans and Social Security.

If Social Security income is all you received for the year, then you probably do not need to file a tax return.  Social Security income is non-taxable unless you have other taxable income that exceeds a certain amount based on your filing status.

Take a look at the following TurboTax help article to learn more about whether you need to file a tax return:
