Best way to handle a credit card download fiasco

Best way to handle a credit card download fiasco

Hi there,   hoping that someone knowledgable with book keeping can give me the answer here.

One of my credit cards has been integrated with Zoho books and we have been downloading transactions with no issue.  The credit card got compromised and was used fraudulently so we reported this to Chase, and they cancelled the card and sent out a new one.  When they did this, the changes that were done to the account created a new credit card and I had to reconnect to this new card.  That created a new liability account in our chart of accounts for the new credit card.

I'm now doing my taxes for the past year, and I find that the old credit card account is there, as is the new one.  But for some reason, the transactions of the old card only go back 3 months and not to the start of the financial year.  I can get those transactions manually through the credit card portal account, but what I need to do is basically delete the old credit card account entirely from our balance sheet, and use the new one but load in all the transactions into the new account that are missing from the portal.  I can certainly edit a CSV file for this, but how do I delete an entire credit card account from the chart of accounts?

Any help is greatly appreciated.
