Moved from the Creative Cloud to the Photoshop forum. They will be able to help you here.
Are you using an english version of photoshop cc.
In the english version it's on the top of the list for Sharpen filters, but for example, in a spanish language version it's the fifth (5th)
filter on the sharpen list.
There should be six filters on the Sharpen list, so if you have a non english version of photoshop cc, you might just try all six, since sometimes names
get lost in translations.
In Photoshop, when you click Help > About, does it report version 13.x or 14.x?
If version 13.x then you're running CS6 and there will be no Shake Reduction.
If that's the case you'll need to download CC (version 14.x) from the Cloud.
