Capital loss carryover - when you enter Schedule D, line 21, Allowable loss, should it be entered as 3000 or -3000?

In TurboTax, on the loss carryover screen, you should enter the capital loss carryover amount as a positive number.  On the Schedule D, the loss carryover with print as a negative amount.  Please see the screen shot attached.

And you shouldn't override line 21.  Let the program calculate it.
