There is no font family in the Adobe Fonts (formerly Typekit) service by the name of Futura Std and never was.
If you had such a font family previously, you licensed it is some manner other than via Adobe Fonts. There is a Futura Std family available via the Adobe Font Folio 11 product, but for a number of years, Adobe no longer licenses that font separately. And Adobe never bundled that font with any applications. I suspect that either (1) you previously licensed that font and successfully used it with your documents or (2) edited documents using those fonts from an InDesign package where those fonts were physically located in a subdirectory named Document Fonts.
