Where to declare reversed 80C exemption on house sale

I have sold a house within 5 years of purchase. In the previous years of ITR filing, I have claimed 80C deductions for repayment of principal on the house loan. I understand that these deductions will now be reversed and treated as income in the year of sale. 

My questions are:

1. Where should I declare this as income in the ITR filing? 
2. Does this additional income qualify for advance tax calculations as well?

Thanks
