What is with form/page 3805E on CA state form I don’t need and can’t get rid of it help!

This appears to be coming from an entry in the Federal screens.   Go under Less Common Income and revisit Installment Sales. Delete the erroneous installment sale entry.  This should get rid of the form on the CA return.

If you do not need CA Form 3805 E, you can delete it by following the steps below:

5. Click on "Delete Selected Form" and then "Continue"
6. Scroll down and click on "Continue with my return"
