1099-INT and 1099-DIV for Traders of Secuities (MTM)

I've searched but can't find an answer for this.  I have a dedicated brokerage account that I use exclusively for my 475(a) elected trading business that I've previously reported on a Schedule C.  This year, the account kicked off both reportable interest and dividends.  How do I report those for the business as in my mind they should be considered business income, and not personal income?

 

Thanks
