As far as the IRS is concerned, all that money was earned by you while you were self-employed and in business for yourself. You'll report it on a SCH C - Business Income & Expenses. So start under the Business tab and begin working it through. Note that a 1099-MISC is not necessary. When self-employed, the IRS expects you to keep your own records and use them to complete your taxes with.

You'll have questions as you work this through, if this is your first time. Just post back with said questions, and we'll do our best to help.
Also, get an EIN for your business. It's free, takes about 10 minutes at <a rel="nofollow" target="_blank" href="https://www.irs.gov/businesses/small-businesses-self-employed/apply-for-an-employer-identification-n...>
That way, if you ever have a requirement to issue any tax reporting documents (such as a 1099-MISC) you use your EIN on those documents, and not your SSN. The last thing you want is to be providing your SSN to people you may not even know.
