I cannot locate the payers tin on my social security 1099

You are trying to enter it in the wrong place.

Go to Federal> Wages & Income>>Retirement Plans and Social Security  (SSA1099 and 1099RRB) to enter your SSA1099.

If it's asking for an EIN number you are entering it in the wrong place. There is no EIN on social security SSA-1099.

If you only get ssi or SS or SSDI it is not taxable and you do not have to file a return. 

Try going to the search box and type in SSA-1099 or Social Security Benefits.  That will give you a Jump To link to take you directly to it.

OR

Enter a SSA-1099, SSA-1099-SM or RRB-1099  under

Federal Taxes on the left side or top

Wages and Income

Then scroll down to Retirement Plans and Social Security

Then the second line - Social Security (SSA-1099. RRB-1099) - click the Start or Revisit  button
