You can deduct ordinary and necessary business expenses. That means expenses that are a normal and regular part of the particular job you are doing. A travel agent working from home can deduct certain household expenses as a "home office". You can deduct phone and computer expenses (much easier if you have work-only computer and phones). You normally wouldn't deduct gas for your home's lawn mower because that is not a business expense for a travel agent, even though it might be an expense for a landscaper. If you decorated your home office with a $50,000 Picasso print, that would not be an "ordinary" or necessary expense.
Unemployment compensation is taxable income, make sure you get your 1099-G from your state government to include it (you may have to download it yourself if the state does not mail it).
As a small business person, you can take a special self-employed business deduction for your medical insurance expense. There's an article here.
