You must include the income and enter the income on a Schedule C whether you had expenses or not. When using the online product, Schedule C is only available in the Self Employed version. You must pay self employment tax on the 1099-MISC income if it was more than $400. Check out the Freedom edition in my answer if you think you qualify for it. It is free.
Or you could buy and download any version of the CD/download product and install it on your computer. All of those versions have Schedule C.
