Deductions & credits

What if my Medicare premiums are more than the proceeds from my business? I went through this last year and couldn't figure out a way to take part of the deduction against my business and part as personal deduction. Is there a way to make that work?

Or maybe that's irrelevant. IIRC, I've been using the Standard Deduction ever since the SD got raised. It's still useful on my state income tax (Calif), though.
