How to edit your extension on Turbo Tax? I have added in some information in incorrectly and need to adjust it.

Once the extension request has been filed it cannot be edited.

If you are located in the US the last day to file an extension was April 18, 2023.

If you are located outside the US the last day to file an extension was June 15, 2023.

Not sure what you mean by "edit the extension" ... once filed you cannot adjust the filed extension form.   Now if you mean you have continued the return and have added information since the extension was filed then you can continue the process and make any needed adjustments/changes before you file the finished return.   When you log in,  if you are not given the option to continue the return, scroll down and click on ADD A STATE to open the file.
