I know that there are lot of question have been asked on this topic but my concern is that after following all the available options Forms are still not appearing on Form interface.   
However I can see form under content tree.

**Other Details:-** I am using Sitecore.NET 9.0.2 (rev. 180604) and also using Sitecore Forms Extensions for Sitecore 9.0-1.8.2

I have performed the following the steps:-

* Rebuilding master indexes
* Renaming Sitecore forms
* Check the Form folder id in core database, ID matches
* Clear browser cookies
* define "is\_template" field from "istemplate" field

I have taken the references from the following URLs and Sitecore StackExchange questions: -
