You did NOT pay 10% on the unemployment you only had 10% withheld just like you have withholdings on your paycheck. How much you will get back as a refund depends on the total income you had all year, what your filing status is, what your other credits will be and all the payments you made (like the withholdings) so your question really cannot be answered. Complete the income tax return to see what your bottom line finally is.
