How Does One Get the Render Tickbox to Show up?

[One&Done]

Have black mask shapes, rather than transparent.

Need to locate, or know how to get the Render tickbox/checkbox to appear.

I looked everywhere until my eyes hurt.

Thank you much

Apparently by clicking on the deepest layers this buried render box shall be revealed.

Did Mylenium's suggestion help? If not, can you please provide more information?

For example, are you asking how to export video with alpha? Or you asking about something inside AE?
