I did complete both parts I and II of form 6252 in 2017. Part I - the Gross Profit and Contract Price, and Part II - the Installment Sale Inocme for 2017. Now, I'm trying to complete only Part II for 2018 - the Installment Sale Income for 2018. I don't see how/where to do this. TT Online is only asking about Part I information. I don't see find where or how to enter the Part II info.
