I have several checks posted to the wrond account, how do I corect this?

You can create a Journal entry to move the checks to the correct account, a-hawk.

Here's how:

1. Click + New.
2. Select Journal entry.
3. Select an account from the Account field. Depending on if you debit or credit the account, enter the amount in the correct column.
4. On the next line, select the other account you're moving money to or from. Depending on if you entered a debit or credit on the first line, enter the same amount in the opposite column.
5. Enter information in the memo section to know why you made the journal entry.
6. Select Save and close.

I recommend consulting your accountant on specific accounts to use when recording the transactions. 

Moving forward, update the account configurations within your accounting preferences to ensure they're correctly mapped to their designated accounts, preventing future discrepancies. Here's how:

1. From the Gear icon, select Payroll settings.
2. Scroll down to the Accounting section, and click the Pencil icon.
3. In the Paycheck and payroll tax payments tab, hit the Pencil icon.
4. From the Bank Account drop-down, select the appropriate account.
5. Click Save.

You can also reconcile your accounts and see updated data that matches the corrections.

Using QuickBooks Desktop, you'd just edit the checks and change the bank account. I wonder why QuickBooks Online isn't like that, and instead makes it so hard?
