It's not a simple yes or no question. 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, if any.
If your only income is SS, it is not taxable and you do not even need to file a return (unless you are married. Then it would depend on your spouse's income)
