I'm here to provide some ideas on how to handle your bank accounts in QuickBooks, @WOODS Edge Creations LLC.

If you're going to use the same register, we can disconnect your old bank account. Then, reconnect it with the new sign-in info and use the same register. 

Here's how:

1. Proceed to the Banking menu. Then choose the Banking tab.
2. Click the tile for the bank account.
3. Select the pencil ✎ icon, then click Edit account info.
4. Press the Disconnect this account on save checkbox. Note: If QuickBooks is downloading new transactions, you won't see this option. Wait a few minutes for the update to finish and try again.
5. Select Save and Close.

Once done, you can now connect the account with the new sign-in info for online banking. Then, exclude some transactions that are already in the register to avoid duplicates. 

Here's how:

1. Go to the For Review tab.
2. Mark the box next to each transaction you want to exclude.
3. Select Exclude from the pop-up at the top.

Once QuickBooks downloads your transactions, you'll want need to review and categorize your transactions to make sure they’re categorized accordingly.
