I had a 1099 R but then rolled over 100% of the distribution why does it show as taxable?

I took a distribution from my 401(K) account from a previous employer and have a 1099-R for that.  Within the 90 day time line I rolled over that distribution into a IRA with the full balance including the tax that was withheld.  Why does that amount show up a income on my tax return?

The time limit for a roll-over is 60 days, not 90 days.  The withdrawal is a taxable event.
