Hi, that message on the wizard usually means the mapping fields were not generated yet, so the guide has nothing to finish with. On the Create New Integration Mappings page there is a step where the field list gets generated first, then Next, then Finish. If you jumped straight to Finish, or the page lost the previous step, that is exactly what you get. I would close it and walk the steps again from the start.
The other thing I notice is your job queue behind it, plenty of Error and On Hold. Those on hold ones only wake up from changes in BC, changes on the Dataverse side don't restart them, so they can sit there forever looking fine. Check Integration Synchronization Errors first, the details there are usually clearer than the wizard message.
This page has the troubleshooting side: https://learn.microsoft.com/en-us/dynamics365/business-central/admin-troubleshoot-sales-synchronization
Glad to help - follow up if anything is unclear.
