Hello @Jim Dalrymple ,
Welcome to Microsoft Q&A forum.
Looks like you are creating a new project in SSMS? If so, I think you may need to try to create the SQL Server Database Project in Visual Studio.
Not very sure the edition of VS that you are using, in VS 2017, the SQL Server node mentioned in the document exists, see following screenshot:
And in VS 2022, you can directly search for the SQL Server Database Project(make sure that the "Data storage and processing" workload has been installed, VS Installer > Modify > Workloads).
