If that is your only income, you don't have to enter it or file your tax return at all.
If you are required to file for other reasons, here's data entry:
-
Federal Taxes
- Wages and Income
- Scroll
down to the Retirement Plans and Social Security
- Select Social Security (SSA-1099, RRB-1099)
Note: Whoever claims your as a dependent - they don't report your SS benefits either.
