Examine Form 1040. The entire $15,095 is considered to be income, but if only $95 is in box 2a of the Form 1099-R, you should be seeing only the $95 of taxable income being included on Form 1040 line 5b. Also, box 5 of the Form 1099-R should have $15,000 in it. Check to see that all of the boxes on TurboTax's Form agree with those on the Form 1099-R provided by the annuity company. Make sure that you have not marked the IRA/SEP/SIMPLE box; the code D indicates that this is not a distribution from an IRA annuity.
