Trying to file business taxes after filling personal, social has been a problem, what do I do?

What kind of business return -- Schedule C?

When referring to a business return, do you mean Schedule C--you are a sole-proprietor?

If so, Schedule C is part of your 1040 return, not separate like returns for partnerships and S-Corporations.

Schedule C is filed with your personal return.  If you are trying to e-file again, you're probably getting the message that a return has already been filed with that SSN.
