Looks like you have thoroughly gone through this process.
You mentioned a CD. If you are using the TurboTax desktop CD/Download editions you are not limited in the number of tax returns that can be created, completed and filed. The limitation is that you can only e-file 5 federal tax returns using the desktop editions. Any returns greater than the 5 have to be printed and mailed.
If you are using the desktop editions then you can go to Forms mode by clicking on Forms. From the Forms mode screen you should have been able to delete the Asset Entry Worksheet for the Schedule C activity. That would have removed the asset from the Form 4562.
