If you made loans to your C-corp, the company should have issued you a Form 1099-INT, which you would report on your personal tax return as interest income. There is no deduction for making loans to a company, even if you 100% of the stock. If you paid expenses for the business, with personal funds, you cannot deduct them on your tax return. In order to get a tax deduction you will need to have the Company reimburse you, and the Company can deduct them. As for Home & Business vs Self-Employed, based on what you described you don't have anything to report on a Schedule C. That said, there are minor differences between the two, but the biggest difference is that Home & Business is software that resides on you computer, while Self-Employed is internet based.
