Enter Cash Income
You can include the other income as cash on your return and you will not need the 1099.  To do so, follow the steps below.

Go into your account with Turbo Tax
Select Federal Taxes, then
Select Income and Wages, then
Scroll down and select, Self-Employment - Income & Expenses -  Start
Say YES to Did you have Self Employment Income (if that screen comes up)
Then Tell Us The Type Of Self Employment Work You Do, here you can put in a description and Continue
The next screen will be Let's Get Income, here you will select 'Additional Income'.  This is for cash income.  
Then continue as you normally do with your return.

But if you have any expenses to write off against it you will have to upgrade to the Self Employed version.
