I purchased 1.99 of extra storage and it’s not showing up

Purchasing iCloud storage adds storage to your iCloud space, which is used for backing up, and for syncing. It does not add any storage to your phone, which will never have more than it did when you bought it.

See→What's the difference between device storage and iCloud storage?

Please recheck the Apple ID that you are using on your device. Each iCloud is associated with an Apple ID. If you change Apple ID iCloud Storage will also change.
