Do i need to add my unearned income

Simple answer: yes.

But taxes aren't simple. 

Social security only becomes taxable when added to sufficient other income. If you are otherwise required to file a tax return, you do need to enter it in Turbotax (TT). TT will determine the taxable portion.

Social security (including SSDI) becomes taxable when your income, including 1/2 your social security, reaches:

Married Filing Jointly(MFJ): $32,000

Single or head of household: $25,000

Married Filing Separately and lived with your spouse at any time during the tax year: $0

After TurboTax (TT) calculates the taxable portion of SS, it puts the total amount of SS on line 6a of form 1040 and the taxable amount on line 6b. TT also produces a worksheet  to show how the taxable amount is calculated. Although most people pay tax on 85% of their SS. it can be less for lower income taxpayers.
