I need to file 1040x for efiled return on which estimated payments were deducted

I cant find the box to activate the original return amounts for income etc, but the return only shows the revised liability and payment amounts and corrected refund.  I cant seem to find the box to use the return amounts as originally filed as in the past.

Also, can the program allow electronic filing for the 1040X?  I thought I read that the Service was accepting this recently.

Thanks
