Sale of mobile home in California and turbo tax premier

I am using Turbo Tax Premier and I am trying to report the 2023 sale of a mobile home in California which was registered with the Department of Community Development.  We owned the mobile home for many years and used it as a vacation home but for the past two years stayed there less than 14 days per year due to my wife's increasing health problems.  We never rented it out.  Should I enter it as a second home under the theory that we used it at least 10% of the days that we rented it out, even though we never rented it out?  If it shouldn't be reported as the sale of a second home, how should we answer TurboTax's question "What type of investment did you sell?" Would it be "other"?
