Where can I watch Margo’s Got Money Troubles?

If you mean the TV adaptation of Margo’s Got Money Troubles, the official place to check is Apple TV+ — in the Apple TV app or on Apple’s website. If it’s available in your region, it would typically require an active Apple TV+ subscription.

Because release timing and regional availability can change, it’s worth confirming on the official Apple TV+ page before trying to watch. If you meant the book instead of the adaptation, that would be available through bookstores, ebooks, and libraries rather than a streaming service.
