Turbo tax needs a federal ID number for my social security benefits, but SS tells me there is no such number for SS what should I do?

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.

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
Wages and Income
Then scroll down to Retirement Plans and Social Security
Social Security (SSA-1099. RRB-1099) - click the Start or Revisit  button

Screen shot added above.  You want the first line not the Other 1099G Income.
