on the logic pro session the vocals are not recording in wave mode

You listed 2 problems: 1. Your project file not found; and 2. Your vocals are not being recorded as Audio.

Problem # 1:

1. Open your username folder, and in there open the Music folder, and in there open the Logic folder.
2. The Logic folder is the default where all your projects are saved.

Problem #2:

1. Run Logic and add a new Mic/Line track under Audio
2. Click on the R in the new track to arm it for recording.
3. Press R to begin Recording. After the default 1-bar count-in, begin singing your vocal.
4. Press Cmd + S to Save your new project.
5. If you Save your new project to somewhere other than the default Logic folder, then the next time you want to open your project, you'll have to use "File, Open Recent >" or navigate to the folder which contains your project.
