Most likely they want a P & L ( and probably your business bank account statements) for the business showing your income to date since you do not have a W-2 ... they have to verify your income in some way ... and you DO have a business. They may also want proof that you actually made the income you reported on the Sch C as well as supporting docs for any expenses claimed ... again to verify you have an income to support your ability to payback the loan.
