Can anyone help? I am submitting my return for Review, but it keeps bouncing back to me to fix documents. It has something to do with the Schedule C..

This same thing happened to me. What I did to finally fix it was delete my 1099MISC and re-enter it and answer the questions it prompted me to answer. I think the first time I did it I answered some the questions wrong and it thought I needed a schedule C but I didn't. Hope this works for you too!
