ZackE.  You are completely incorrect.  Per other admins and trial and errors, you can import a simple budget OR create a subdivided budget.  You cannot import a sub-divided budget.  Earlier this month we upgraded our version of QBO to Advanced based on uninformed posts like this with the hopes of importing a budget sub-divided by class instead of typing it in manually.  After trying to do it in the Advanced version, it is clear that you CANNOT import subdivided budgets as we were mislead to believe.

We are going to downgrade our version and demand a refund.
