What to enter for Depreciation for expensed assets with Sale of Business Assets Form 4797

Self-employed with business website and domain. Stopped working previous year due to disability. 

Following year, selling website domain and website content (not entire business). 

Filling out form 4797 in turbotax.

I expensed both in previous years -- website & domain as advertising costs.

  1) What do I put in the field for "Depreciation taken on this property"?  0??

 

2) Next question asks if this is property I took a depreciation on. It's not. Very confused what to do here.

 

3) Figure I can still expense costs to maintain the website like hosting fees. Do these get taken off price of sale or in regular business expenses?

 

Thanks!
