I have to Enter a bill where an E-Commerce portal has raised a commission invoice on me and on the same invoice deducted TCS on the sales done through them. How to Enter?

We sell our products through an E-Commerce portal. They have collected the payment on our behalf and paid us deducting Commission and TCS. I need to enter the Bill showing the TCS deducted amount and that I have received the full amount for the said Invoice raised by me.
