Hi @Rivet1 !
You can enter your business expenses into TurboTax during the interview/EasyStep process (depending on which version of software you're using). To do this:
- Select the Search bar (binoculars icon), and type in business
- Select Business or Professional Activities, then select Go
- Continue answering questions to enter your business information (if you haven't done so already)
- In the section after Vehicle CCA, you will start to get questions related to your business expenses (starting with paying for advertising)
Hope this helps, and happy filing!
