@itonewbie and @George4Tacks .

Thank You both for your replies.

Update --->

I followed your provided instructions & quickly realized that I had already been to this menu area (within the software) before posting the initial question.  I clicked the data entry field and got the screens (or dialogue boxes) shown in the attached screenshots (below).

At this point, when I click the "+" sign, should I be seeing a drop-down of all the preparers that I have already entered & configured in the software?  That's not happening.  (I wondered if you were supposed to manually type in the correct info.  That does not seem to work).

The other issue that may be a factor is:

Is this feature/function supposed to be accessible regardless of whether the user accesses Intuit ProConnect™ on a desktop, laptop, tablet, or mobile device?
