Yes, you have to file a tax return, because you have a 1099-Misc with more than $400 in box 7. You do not have to report Social Security disability income (SSDI) because the rest of your income is low enough. But, since you have to file anyway, go ahead and enter your SSA-1099 and let TurboTax generate the worksheet that shows that none of your SSDI is taxable.
If you have some other kind of disability income, other than SSDI, you need to identify what kind and what paperwork you got (W-2, 1099-R, etc) and your age.
