You can't....what is recorded on a track is there forever unless you use editor and try to erase just the vocal sine wave....good luck with that. I would suggest yo use individual tracks, as many as needed, and then go back and edit out what you don't want from that paarticulaar track and leaving your other tracks as you like the to be.
Can you explain further what you did and have? It is not clear to me why you have an echo or why you have a repetition of a recorded voice? I will take a guess.
When you record, you can record in stereo or mono. If you have 2 microphones, one for each channel, they will be on one track, but on the left and right channels. If there is a slight delay in recording on one of the channels, then you would probably get an echo effect. Is this what happened?
If so, then you want to get rid of one of the channels. Open the file in ACL and click on Stereo. Then under the Effects tab, open Stereo/Phase and select Split Stereo Channels. This will separate the 2 channels into separate objects. Select the one that you want to delete, delete it. Save the file with a new name. Make sure you have a backup of the original somewhere.
If both recordings ended up on one channel or on both channels, then nothing can be done.
I left it as it was. Now when I record I turn off the sound card ("Realtek") and make a record from just system audio.

I wasn't aware that Realtek made soundcards, so lets assume that they do....a soundcaard, properly configured should enhance your musical experience, not have you turn it off ! you shouldn't lleave something the way it ws if you are unhappy about it....work with your issue a litatle bit more and get bac to us if its still broke....and turn that soundcard back on....you paid good money for it.
