I have multi-transactions on my account and I dont know how to match then for the balanse sheet as can not edit them after creation. Do I need to delete it?

It's nice to see you here, @userstorage123reg,

I want to help you correct your account balances to correct your Balance Sheet data. I just need some more information about what these entries are and what are they for. Kindly share some more details or screenshot of the problem in the comment below.

In the meantime, if you're referring to duplicate transactions in the register, then yes, you can delete them. Also, the dupes might result from adding online banking entries and not matching them to the entry in QBO.

The only way to avoid any duplicates is to exclude them in the For Review tab. 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.
   

Excluded transactions are then moved to the Excluded tab, and won’t be added to QuickBooks or be downloaded again. To permanently delete duplicate entries, put a check mark on them, then hit Delete.

Also, you can delete and recreate a rule if you think it's causing the duplicates. This will refresh the connection and get rid of any corrupted list. Here's how:

1. From left menu, click on Banking.
2. Go to the Rules tab.
3. Look for the rule then click the drop-down arrow beside Edit. 
4. Select Delete and Yes to confirm. 
   
5. To recreate a rule, click New at the upper-right section of the Banking page.

Message me again in the comment so I can check on you again. I'll be waiting for your response as I want to ensure this is resolved. Have a good one!
