Where do I enter Company paid fees from 1099-DIV?

do you mean dividend reinvestment fees or other fees on the 1099? sorry no longer deductible through 2025 for federal. your state may allow them

Your company fees are entered on the Schedule A Itemized Deductions under Miscellaneous Deductions for broker fees.   Unless you Itemize, you won't be able to take advantage of this deduction.
