Social Security Retirement/Disability/Survivors benefits are reported on a form SSA-1099 and the benefits received are to be entered on a federal tax return. The benefits may be taxable depending on the amount of other income you have entered on your tax return.
However, if the Social Security benefits are the Only income to be reported on the tax return, then there is no reason or need to file a tax return.

To enter Social Security benefits reported on form SSA-1099

• Click on Federal Taxes (Personal using Home and Business)
• Click on Wages and Income (Personal Income using Home and Business)
• Click on I'll choose what I work on (if shown)
• Scroll down to Retirement Plans and Social Security
• On Social Security (SSA-1099, RRB-1099), click the start or update button

Or enter ssa-1099 in the Search box located in the upper right of the program screen. Click on Jump to ssa-1099

If the Social Security benefits  is your ( and your spouse’s if married) only income then  there is no need for you to file a  tax return UNLESS one or more of these apply :

• You had federal/state taxes withheld that can be refunded
• You received advance premium tax credit for health insurance from the ACA Marketplace (aka "Obamacare") 
• You took money out of Health Savings Account (HSA) or Medical Savings Account (MSA).
• You are married filing a separate return from your spouse and you lived together during the tax year OR   you are filing a joint return and the spouse has income other than SS benefits.
