Hi there, carol20. I'm here to share additional insights about this.

In QuickBooks Online (QBO), the default Accounts Payable (A/P) is created during a company file setup or selected during conversion. To ensure your books are organized, it's recommended to use a single A/P. However, we're unable to set or change the default. 

With regards to reclassifying your entries, only Advanced and Accountant users have this tool. You may want to consider upgrading or inviting an accountant. 

Alternatively, we can merge the two A/P. Beforehand, keep in mind that this process is permanent. 

To start, let's determine which one is the default. To do so, pull up the latest bill created in QBO. Then, run a Transaction journal report. From there, we can check which one the program uses. Here's how:

1. From the Expenses menu, choose Bills.
   
2. Select Unpaid or Paid to locate the entry, then double-click it to open it.
   
   
3. Go to More and then Transaction journal.
   
   
4. Review the report to verify the details.
   
   

Next, we can start merging them. Make sure you’re in Accountant view. Then, take note of the details of the winning account. I'll show you how:

1. Go to the Transactions menu, then Chart of accounts.
2. Find the one you want to keep. Then, select the drop-down arrow in the Action column and then Edit.
   
   
3. Note the Save account under (Account Type), Tax form section (Detail Type), and Account name (Name) of the account. These must be the same between the accounts you want to merge.
   
   

If you have all the info needed, let's handle the duplicate:

1. Go back to the Chart of accounts page.
2. Find the duplicate (the one you won't keep). Then, click the drop-down arrow in the Action column, then Edit.
   
   
3. Change the Account name and Tax form section so the duplicate info matches the one you want to keep. 
   
   
4. Hit Save, then Yes, merge accounts.
   
   

Once done, it merges the two, so you end up with one. QBO moves past transactions from the duplicate to the account you want to keep. For more details, please see this article: Merge duplicate accounts, customers, and vendors.
