Is social security taxable? i was taxed $1,350 on return question 6b. i filed hoh with 2 dependents (including myself an 1) should my standard deduction been $21,950 ?

Between 0% and 85% of Social Security is taxable. It depends on your filing status and how much other income you had besides Social Security. 

You can use the IRS Interactive Tax Assistant to see how much of your Social Security is taxable.

You are never your own dependent. So your Standard Deduction can not be $21,950. What your Standard Deduction depends on your age. Please see the IRS Interactive Tax Assistant for help in finding your Standard Deduction.

Remember not to count yourself as a dependent.

in turbotax there should be a worksheet that computes the taxable portion of your social security benefits. there may be a fee to see it. $1350 is the taxable portion of your social security. for HOH some of the social security benefits will be taxable if adjusted gross income (without line 6b) + tax-exempt interest line 2a plus 1/2 your social security benefits exceed $25,000.  your standard deduction does not figure into the computation of the taxable portion.  and the taxable portion once it's computed that a portion is taxable involves a more complex computation.
