Filing amended tax return - does that increase audit risk?

[Anonymous]

For complicated reasons, the schedule C didn't end up getting filled out and filed for a sole proprietor business I own in its first year of operation. A refund is therefore due to us on our federal and DC taxes, because the business expenses were higher than revenue that first year. Anyone know whether filing an amended return sets off red flags and is likely to lead to an audit? If so, I don't know if it would be worth the hassle to do it. (An internet search suggests that it shouldn't trigger an audit, but I'm wondering if anyone here has any reason to think otherwise.)
