A QBO Paychk List net pay amount (and amt posted to QBO bank register) differs from amount posted on a check by QBO; which has already cleared the bank. How to resolve?

Hello there, @tah-difinitigrou!

You can delete the check directly from the Paycheck List menu and recreate it with the same amount of the check that has been cleared to your bank. I'll show you how.

1. Go to Workers.
2. Select Employees.
3. Under Run payroll, select Paycheck List.
4. Find and open the said paycheck.
5. Select Delete.
6. Click Yes.

Once done, you can go ahead and recreate the paycheck. Make sure to enter the same date for accurate data reporting. You can read through this article to learn more: How do I create a paycheck for an employee?

Lastly, here's an article you can read for ideas about your payroll account management: Help Articles for QuickBooks Online Payroll.

Keep me updated in the comments if you have any other questions. I'll be here to lend a hand.

No, I've been around this block before - from one of my previous posts (and I've confirmed it again on this issue) - one cannot delete a paycheck once beyond the pay date.
