Your edited files should be stored on your drive either on your computer or an external (if that is where you are storing them). You can confirm the location by righ-clicking on an image in the Library module and selecting Show in Finder. Your Lightroom Classic catalog is connected to you via your Adobe ID (usually your email) and is usually in your Pictures folder. Once you have confirmed where your catalog files and your image files are located and you have also confirmed in your account settings that you have two separate accounts it may be best if you intiate a chat with Adobe to cancel one of the plans. You can start a chat under your profile in your Creative Cloud dashboard icon in the upper right corner.
