You most likely have multiple source /.../setup.bash lines the .bashrc file in your $HOME directory.
Additionally: we see mentions of melodic, jade, noetic and kinetic.
Those ROS versions cannot be installed on the same version of Ubuntu (or Windows for that matter), so something must have gone wrong. Have you tried to follow multiple installation tutorials, for different versions of ROS?
To rectify this situation:
.bashrc file, for instance using nano: nano -w $HOME/.bashrc (I'm assuming you don't have a GUI for your Linux install, as you mention you're using Ubuntu in WSL on Windows 10, if you do have a GUI, you could use gedit $HOME/.bashrc)you should see something like this:
source /home/waypoint/turtlebot3_ws/install/setup.bash source /opt/ros/melodic/setup.bash source /opt/ros/melodic/setup.bash source source/opt/ros/jade/setup.bash source /opt/ros/kinetic/setup.bash source /opt/ros/kinetic/setup.bash source /opt/ros/noetic/setup.bash
For now, just remove all of those lines (using the backspace or delete keys). Then save the file using ctrl+o, enter, ctrl+x.
If you did it correctly, the errors should be gone.
At this point you probably want to verify you've actually installed ROS, as the errors you show seem to indicate your install wasn't successful, and some important files are missing.
What's the output of ls -al /opt/ros/{melodic,noetic}?
