Debit note seen in GSTR2A

If it is showing in your GSTR-2A then it will be related to your purchases. Effect will be taken in GSTR-3B

So do I need to make any entry in GSTR 1 for that ??

Will i have to issue a credit note  in 9B in GSTR1 against the debit note in gstr 2A ?

No entry in gstr-1 

The seen is I had purchase a flight ticket in the month of February 2022 for which I had claimed the ITC for the same.

But due to some reason I had to cancel the flight ticket in May 2022 so I have recieved a credit note as well as debit note for the same invoice number so was confused regarding what to do about it.

So I should just make the correction for the same in 3B only na ..nothing else is need to be done for it ?

Reverse the ITC in gstr3b. That's it

Ok sir thank you so much.
