Signing up for a seller account

I’m registering for the professional seller account at 39.99/mo and not really sure what to put for business type.

I have a business that I got a fictitious name statement for to use as a DBA, but don’t have an LLC or EIN. If I choose “None, I am an individual” it says that this can’t be changed later. What if I decide to get an LLC down the line? I won’t be a let to change it to “Privately owned business” if that’s the case.

What would you guys recommend I do? Thanks!
