You just said you have a small business. That is self employment. If you got a 1099Misc for it that is self employment. Or are you doing a separate Business return like a 1065 Partnership or LLC or 1120 S or C corp?
if you have a small business, any income you earn through that company is income that is earned by you an is considered self-employed. It has nothing to do with being a full time nurse, they are separate.
