Every time I go the review and try to delete a line I added on accident to self employed section it freezes and doesn’t let me delete it. How can I delete something I added on accident?

The best way would be to go back to the Schedule C (self-employed) section and delete it from the input screen instead of through the final review.  

Use these steps to go back to that section of your return:

• 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
