Home Office

I work from home and have had some office expenses. 

I fill out the home-office questionnaire on TurboTax - which was quite time-consuming (needed lots of data).

In the end, there was NO change to my tax liability. 

I talked with a friend of mine who is also using TurboTax; she has a much lower income than mine, but the result was exactly the same as mine, i.e., no impact.

Is TurboTax working properly? 

Thank you.  Patrick.
