Schedule C is for disregarded entity and sole proprietor independent contractor self employment or Single Member LLC etc. It is under your ssn and part of your 1040 personal return. (If you were a corporation you would be filing a 1120 or 1065 business return.)
But if you filed it on Schedule E as rental income instead of schedule C I don't know if that was right. It could be ok and you just need to tell the IRS it's on E.
