Turbo Tax used the wrong amount when figuring how much of my SSA benefits should be taxable. Line 19 of the IRS worksheet should be the smaller of line 17 or line 18.

Line 17 is $22,080.30 and line 18 is $22,715.40. Turbo Tax used $22,715.40, so both my federal and state returns are incorrect. How do I get them to fix this?
