How do I find my converted file? (Word - docx)

Have converted (twice at least) an Adobe file to a Word docx format......instructions say to choose "Office 365" or "SharePoint" and then put in my account URL.   I do not know what Office 365 OR SharePoint are....nor whatever "my account URL" might be.  Have a paid subscription (lowest level) to convert files, but need to FIND and then MOVE the converted file to its proper folder.  Unable to find an "answer" that addresses this, at least in a way I can understand it.  Would much prefer to have Customer Support available to answer my question personally as I am NOT very experienced on computers.  Thx, Pat.
