IRA rollover to same account

I took out $24,100 in distributions from my regular IRA.  Within 60 days, I redeposited $3,000 into the same IRA.

 

It seems to me that the "NET" taxable IRA distribution should be $21,100.  In the entries in TurboTax I answered YES that some or all of the amount was rolled over into the same account. The worksheet shows the entry for $3,000.    Yet, on my 1040, the amount continues to show the full distribution 0f $24,100.  WHY is there not an adjustment for the rollover?
