Hi, in order to submit office expenses you'll need to upgrade to the Self-Employed product. This will then enable you to go into the office expenses menu on the left hand side under the income section to submit the appropriate worksheet. 

Hi @alloowishus 

On the left menu, if you go to Income -> Self-Employment -> Self-Employment Summary, and on the Summary page, click on Edit. Unfortunately you will have to click through the same flow again to get to the Expense section.

Hope that helps!

Are you using the self employed version of TTO? If yes, on your return, go to left -hand side  navigation menu- click on self employment under income and start over, you will see the option for entering/editing the expenses after you are done with the income section.

Thanks for using TurboTax
