Broker commission rebate.

I am a broker.  I offer my clients a commission rebate.  I understand they don't report is as income and i don't issue a 1099.  My question is where do I report the rebate on turbo tax?

 

I understand that the 1099 i get from the closer, or selling company may reflect may only reflect the commission i received and therefore i do not report the rebate on my taxes.

 

If the 1099 shows the total commission paid to me and not the rebate then where do i enter the rebate on my tax form

 

sorry long stuff to ask a simple question

 

Stay safe
