Where can i deduct credit card interst

[ee-ea]

You can't, it is not deductible.

business credit card interest related for business expenses is deducted on schedule C as interest - specifically line 16b

if you use the CC for both personal and business, no interest may be deductible because any payments would first go to pay off personal items

Credit card interest is not deductible on an individual (personal) return.  Business credit card interest related to business expenses can be deducted on Schedule C.   If the credit card is used for both personal and business, it cannot be deducted.
