You have to file a tax return if you have a 1099-misc, for over $400; because social security and medicare tax are due, even if you owe no income tax.
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
