sale of rental property

Getting into a rut!

 

I could not rent my rental property entire 2020 but had it advertised for rent or sale via circulars for during 2020.
 
Under Rental property income, I entered =0; usual + new repair expenses totaled $9K.  Had new cabinets, carpeting, & appliances added to asset value (not expensed).
 
After I entered all rental expenses, I went to Sale of Property/Depreciation, where it asked whether I added to rental properties which were in individual total under $2,500 & other detailed questions which gets the Safe Harbor ruling involved.  Has become complicated.
 
Should I have bypassed this & gone straight to Sold business properties?  
When I proceeded to Sale of Business Property; at cost of Property I indicated what I originally paid for the rental property 30 years ago & added assets additions & closing expenses.   
 
What should I have done?
 
NOTE:  People have answered my earlier question & I mistakenly responded via email.  This probably never got through.  For this I humbly apologize.  But all this is getting a bit much.
Please help.
