Total unemployment benefits received is given in a gross amount, but 10% was withheld for tax - do I enter gross unemployment amount or just what I recieved?

I withheld 10% for taxes, but was hit with drastic change on my return after entering all income sources.  Same percentage of taxes taken from W-2 work, but my refund went negative after entering UI.  The math makes it seem like I didn't pay ANY taxes on my unemployment, so wondering if it's asking for what I received (after withholding) or the gross unemployment amount (before withholding).
