you don't.  even if you upgraded to TT live version.   they can only tell you if your return is correct based on what you entered though some incorrect entries would be caught by the program.  if you failed to enter something, that is unlikely to be caught.

best to review all your entries.   because a typo is very common.    you are filing self-employed,  there is no way for a live agent to know if all the info entered on Schedule C is correct.
