Incarcerated and cohabitating with spouse - where do you answer these questions in the forms

I'm using Turbo Tax desktop version and I'm wondering two things: 

1. When I'm reviewing my tax return, it asks if my spouse has been incarcerated, I click applies to me and then its provides you with a drop down or Yes or No. I try to respond but it says I'm trying to override the cell. I would like to be directed as to where I can answer this question in the forms, please provide form name and line item. 

2. There is a question this year that asked if you are cohabitating with your spouse at December 31, 2020, can you also provide the form and line item where to answer this question.
