Get your taxes done using TurboTax

What is the pros and cons of delaying "opening doors" on my taxes? For example, is there a benefit in adding my expenses and considering them start up costs than filing my expenses now? Would I have to pay more in taxes, the next year because I have opened my doors on my taxes? I have done 1-2 projects for connections I had known but have not done any recruitment for new customers, so I am fully functional for the work I am doing for my current connections but do not have the infrastructure to accommodate new customers, thus not fully functional in that area.
