That worksheet looks simple and is actually very complicated and confusing to a lot of people. Enter your SSA1099 exactly as it appears and let the software do the calculations.
Up to 85% of your Social Security benefits can be taxable on your federal tax return. There is no age limit for having to pay taxes on Social Security benefits if you have other sources of income along with the SS benefits. When you have other income such as earnings from continuing to work, investment income, pensions, etc. up to 85% of your SS can be taxable.
What confuses people about this is that before you reach full retirement age, if you continue working while drawing SS, your benefits can be reduced if you earn over a certain limit. (For 2017 that limit is $16,920 —for 2018 it will be $17,040—for 2019 it will be $17,640) After full retirement age, no matter how much you continue to earn, your benefits are not reduced by your earnings; your employer will still have to withhold for Social Security and Medicare.
To see how much of your Social Security was taxable, look at lines
look at lines 5a and 5b of your Form 1040
