The 1099-misc box 7 nonemployee compensation filing requirement, excludes corporations like Home Depot. For #1, you should exclude corporations from your consideration. All other types of businesses qualify. This is really aimed at contractors who work for you.
#2, I can't say for certain what would happen, but it would not be recommended to report you are not going to follow the requirement. The questions are intended to be a check that the reported information make sense. They are also used for paid preparers to ask the necessary questions.
#3 TurboTax has an affiliated software for filing form 1099s, Quick Employer Forms. However, since the January 31st due date has passed, you will need to file paper. To do so, you need the actual IRS 1099-misc forms, which you can get from Staples (or other type of store).
It's easiest to fill them out yourself, since the form is self-explanatory (your information + the person you paid + amount in box 7). If you choose to file the 1099s, you'll also need one form 1096, to submit copies to the IRS by February 28th due date. Form 1096 is like a cover letter, summarizing the forms included with your information.
