The form keeps taking me to deductions, but I can not find how to enter income for my business that I did not get 1099 for

Hope this helps and the steps are still the same.  Let me know?

How to enter income from Self Employment

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.
