Query on taking FTC relief on dividends received in January23 to March23

I have a few shares of US listed company received as RSU. I have received a dividend of $28.71 (credited $21.53 and tax withheld $7.18) in February-2023. 

The form 1042-S for calendar year 2022, talks about the dividend and tax withheld for the month April-22, July-22 and October-22. Hence, I have proof in order to claim FTC relief on this.

However, my query is, when do we need to disclose the dividend received in February-2023, in AY 2023-24 or in AY 2024-25?
If we need to disclose in AY 2023-24, how can we claim a FTC relief on the tax withheld on dividend received in February-2023?
