permission to baptize 8 year old from parents

Hi,
I am a ward clerk with a question
I heard there is a form that needs to signed, scanned and uploaded to the membership info when a child turns 8 to be baptized but the parents are not members. I do not see or cannot find this form, is this a do it yourself form or is there a form or how shall I proceed as they are asking me for the form. Also I am not aware of how to upload a scanned document to the membership records. Is this even possible?

There are instructions in a new Notice (September 20, 2019) at the Official Communication Library that will answer all of your questions.

In LCR:
[Membership] --> [Create Record]
