I want to enter income myself without review. How do I do this?

You can type it in manually.  But you will not be able to file until you run Review

What do you mean by ''without review''?   If you have entries that say Needs Review and you have already verified the information is correct, you can continue to file.   The Needs Review message does not prevent e-filing.    Before you file, a Complete Check review is ran, so you can ignore the Needs Review messages you see while you are preparing the return.    If you are inquiring about something else, please clarify.
