Why is the Left navigation shorter with a split view?

Why is the Left navigation shorter with a split view? TurboTax User experience is starting to take a "nose-dive".

I lost all the space on left navigation because you are forcing a split window view. I don't care about "Referral reward etc. Atleast give me an option to remove this stupid option. This company thinks they are "too big to fail". I will leave turbo tax if this is the attitude you take

Sorry, I do not see an issue with the left side online menu -

Or...are you using a phone? 

IF so, just don't.

Use a wide screen tablet or full computer.
