How do I erase selections made for financial transactions thought I needed to do this for my side business turns out I didn't make enough to put it on my taxes to all

[AnnetteB6]

First, there is no amount of money which is 'not enough to put it on my taxes'.  You are legally required to report any and all income received during the year. 

You mentioned that it is income for a side business.  Typically that indicates that you are self-employed for that business.  If that is the case, you would be entering your income and expenses on Schedule C.  

Use the following steps to go to the Schedule C section of your return, then choose Delete next to the business name that you entered to delete all entries related to the business:  

• On the top row of the TurboTax online screen, click on Search (or for CD/downloaded TurboTax locate the search box in the upper right corner)
• This opens a box where you can type in “schedule c” (be sure to enter exactly as shown here) and click the magnifying glass (or for CD/downloaded TurboTax, click Find)
• The search results will give you an option to “Jump to schedule c”
• Click on the blue “Jump to schedule c” link
