Hi Dinesh , yes you can show this loss in your ITR and take the benefit of carried forward losses u/s 74.

at the time of filing the return nothing documents is required. it is required only in cases of if department take your case under scrutiny assessment. So you have to keep in record the sale deed for purchase, sale deed for sale it and bank statement or cash payment details in which you have received the payment and paid the payment for purchase

Thanks Arif !
