TCS Return Filing Query

Hello All Respected Experts, Good Evening,
We have received payment on Dec Month (TCS also Collected) and Billed to Customer in Jan 2021.

We have deposit TCS challan on Basis of TCS Collection instead of Bill Issuance and Using RPU software for preparation of TCS return.

Please suggest can we show Payment received from Customer in December and Bill date of Jan, in TCS return of quarter ended Dec2020.
