Adjustment of credit notes

Sir,
I have the following d9ubt.
A sold goods to b in March 21
B returned goods in sept 2021
A raised credit note in Sept 21 and
reported the same in Sept 21 gstr1.
But as there was no liability in fy2021-22. In 2022-23 A has the taxliability for Aug 22& sep months.

Can A adjust/reduce his taxliability with credit notes tax amount
if he can adjust, as monthly liability is less than credit note tax amount , can we adjust/reduce the same in two months. Should we mention any details of CRN. or just reduce the amount and pay the balance amount
