social security benefits

I am filing jointly and my wife and I had 72188 in ss benefits with 11672 total in other income. the social security worksheet in turbo tax shows that only 9201 of our social security is taxable. Does this sound reasonable. When I research how social sec is  taxed they say that if 1/2 of your social security plus all your other income is greater than 44,000 you should expect to have 85% of social security benefits taxed if less than 44000 then it would be 50%. Half my social security plus the total of my other income comes to 47766 but worksheet shows only  9201 is taxable which is approx 12% of my total social security payments
