Deductions & credits

@charjean47 and @MayaD  -- Sounds like you're preparing a personal return which also includes business-related schedules, as I am (in your case, schedule E, and in my case, Schedule C). But then how are you guys able to determine what portion of the tax is to be considered business-related and which portion not.

 

On the one hand, I could do something like look at the current published price of TurboTax Deluxe vs. the current price of TurboTax Home & Business and take the difference, maybe? Even still, it feels a little arbitrary for me. Would it be reasonable to say that, since there's only one fee paid for the whole return but the return includes business taxes, that the entire amount would be deductible as a business expense? Does the IRS provide any guidance on this? I looked around online but what I found from the IRS was pretty vague on this subject.
