Confused on how to enter my self-employed solo/individual roth 401(k) contributions in Business Income and Expenses

I opened a Solo (individual) Roth 401(k) in 2020 and made contributions.

In TTD Home and Biz>Business>Business Income and Expenses>Individual and Roth 401(k) Plans.

 

There are options to enter contributions as either Individual 401(k)  (top choice on the screen) and Roth 401(k) (bottom choice on the screen).  I made Elective Deferrals as an employee.

 

This is probably very simple, but I'm confused if I'm supposed to enter under Individual 401(k) or Roth 401(k). When I look at my plan documents (Vanguard) it shows 'Individual Roth 401(k)' so that seems to me I should enter my contributions in the top choice.
