RV Loan Interest - Where to enter for Web Version

I know I meet the IRS requirements for second home with my RV, however the Web version of Turbo Tax is not as friendly as the desktop Application version for entering this information - as I don't see a way of switching to "Form Mode" and following the following:

 

type mortgage into the search bar 

then click on the Home mortgage worksheet and proceed to enter the data

or in step mode

under deduction and credits tab 

click on i'll choose what to work on

the first thing should be your home and under that mortgage interest 

clcik on start or update.
