I had referenced the 2019 conversion in my original post as a comparison to indicate, simply, what documents that I received for my 2019 Roth conversion (because I felt not all relevant F5498s were provided that year).
It is a non-issue since you respondents confirmed my belief that a Rollover IRA is a Traditional IRA for Total IRA purpose with regards to the Roth conversion forms. Thanks, and sorry for the confusion.
