How do I delete an entry for stock sales that I created by error? I don't see any option to delete it. It keeps showing up as needs review

Try using the following steps:

• 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 “1099-B” (be sure to enter exactly as shown here, including the dash) and click the magnifying glass (or for CD/downloaded TurboTax, click Find)
• The search results will give you an option to “Jump to 1099-B”
• Click on the blue “Jump to 1099-B” link
• Click Edit  beside the brokerage name used for the accidental transaction
• Click Delete or the trash can icon beside the individual transaction that you want to delete
