As the following sentence, Is this phrase correct: 'to fill in blank'?
For example: "But I'm not sure about to fill in blank at agency owner agreement document"
I just want to ask someone what I should put in the blank in a document. How could I say this? Does make it sense? I'm not sure if this is correct.

I think that your example sentence is close enough that we can fix it up before I tell you how I would say it.
You are missing something before "to fill" to be the subject of the infinitive clause and you should put a determiner in front of "blank", like "the" or "this" if you are talking about a specific blank.
You could say:
I'm not sure about how to fill in the blank at agency owner agreement document.
I'm not sure about what to fill in the blank at agency owner agreement document.
I would probably express the idea like this:
I'm not sure what I should put in the blank at "Agency Owner Agreement Document".
