Delayed Full & Final Settlement Payment Not Reflecting in Form 16

Hi all,

My last working day at my previous company was on 7th Mar, 2021. 

Due to covid restrictions, I couldn't travel to my base location to return company assets. So my Full and final settlement was on hold.

Finally, I returned the company assets on 30th Sep, 2021 and I received Full and final settlement payment (Feb & Mar salary + leave encashment) on 27th Oct, 2021.

Please confirm, "Should this Full and final settlement payment amount be counted as income in FY 20-21 or FY 21-22"?

Thank you.
