Hello Jon Holmberg,
Thanks for your question
- Go to the Azure Portal.
- Search for Cost Management + Billing.
- Select Cost Analysis.
You can then filter by your resources. To review which resources are causing billing, see steps here: https://learn.microsoft.com/en-us/azure/cost-management-billing/understand/review-individual-bill?source=recommendations
You can also create a billing request here for free: https://azure.microsoft.com/en-us/support/create-ticket. In the link you need to ensure you are selecting a billing type of ticket. This service is completely free and they will assist you in identifying why or assessing the situation.
You can mark it 'Accept Answer' and 'Upvote' if this helped you
