No, the SSA-1099 is not the same as a W-2 and they are entered in different places in TurboTax.

To enter your SSA-1099:

• Click My Account (Top right of your screen). 
  
• Select Tools.
• In the pop up window, select Topic Search.
• Select Yes, let's work on Social Security benefits and click Continue.
• Check the first box, Form SSA-1099.
• Enter the amounts for yourself and your jointly-filing spouse, if they received an SSA-1099 also.
  
  • SSA-1099s for children and other dependents are not reported on your return. They should report it on their own return, but only if they're required to file a return for some other reason (this is uncommon).
• Click Continue. 

TurboTax will automatically calculate what portion, if any, of your Social Security benefits are taxable.

To enter your w-2:

• Click Federal Taxes
• Then click Wages & Income
• Select "I'll choose what I work on"
• Scroll down to Wages & Salaries section and click Start.
• Continue through the interview to enter your W-2 information.
