In the first place you do not report 1099 Div or 1099 Int from IRA or 401k or retirement accounts. You only enter 1099R. Then you only report other 1099Div & 1099Int, 1099B, 1099R etc. under Personal in the Home & Business version. The schedule C you are filling out for Business is part of your personal individual 1040 return. Your self employment business on schedule C is a disregarded entity. The Net Profit or Loss is for you personally.
There might be a box on the Div screen to check for - My 1099 has more boxes.
