You don't have to file a tax return at all, if SSA-1099 is your only income... Is there a reason why you are filing? If you must file for some reason, form 1040A will be generated for you by TurboTax, once you enter the form. You will have to print and mail your tax return, because you can't e-file with zero taxable income - and your social security benefits amount is not taxable, therefore all you will have on your tax return is zeros.
