Sole proprietor business receives 1099 nec on income already claimed on schedule c for business
I claim all business income received from statements and then I receive 1099 NEC forms from some customers for reported income from them that i have already claimed. I believe i must back that income out of my business income claimed on Schedule C. Otherwise it will be claimed twice. Also my 1099 nec forms include sales tax which is not claimed as i come. Confused.
