Not sure what you are trying to do. There is no place on your tax return to say that you are retired, unless you want to use "retired" as your occupation in MY INFO. Occupation has no effect on your tax due or refund.
If you are retired, you can enter retirement income:
Go to Federal> Wages & Income>>Retirement Plans and Social Security (SSA1099 and 1099RRB) to enter your SSA1099.
To enter your retirement income, Go to Federal> Wages and Income>Retirement Plans and Social Security>IRA 401 k) Pension Plan Withdrawals to enter your 1099R.
