Our 2017 taxes has an error and it need to be ammended do I have to pay for that?

Florida has no state income tax, so of course FL did not tax your Social Security.  But it is entirely possible that your Social Security was taxable on your federal tax return, if you had other sources of income along with the Social Security benefits.

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

For your 2017 tax return you can see how much of your Social Security was taxable on lines 20a and  20b of your Form 1040.

For 2018, the form has changed so look on lines 5a and 5b to see how much of your Social Security was taxable.

The answers above are quite correct, but I have to wonder after reading, "Our 2017 taxes has an error and it need to be ammended", who told you that your 2017 taxes had an error and needed to be amended? Did you receive a letter from the IRS? If so, what did it say? Or did someone tell you that Florida does not tax income so you wondered why your SS was taxed on your federal tax return?

I am just concerned that we do not fully understand what brought up your question.
