First, let's get some nomenclature out of the way. A Subform is a Form that is imbedded into another Form. Usually the data is related. So, for example, you may have a Form that returns a person, and then there is a Subform on that Form that returns the person's transaction history. So what you have is actually not a Form/Subform relationship. It sounds like you have two separate Forms.
Secondly, I recommend approaching this differently. If the intention with the Second Form is really to print a scaled down report to give to someone, do not use a Form at all, but a Report. Here is an article from Access-guru Allen Browne on how to do that:

Thirdly, data cannot be stored in Forms or Subforms, only in tables. So any data entered in will need to be stored in a table, unless you plan to re-enter the whole thing again manually at some point in the future. I would recommend adding another field to your table, something like "Pending Approval" check-box, that gets populated when the record is first added, and updated once approved. You can then use this check box in any query where you only want to see approved or unapproved records.
Hope that helps!
