Reconcile Bank Account

In the process of completing the monthly bank reconciliation, I notice there are a few "Liability Check" transactions that continue to show up each month and they date back to 2019 and 2020.  We implemented QB at the start of 2019 and I know we fought our way through some trial and error situations and I am convinced these are some of the missed transactions that just never got cleaned up.  We have verified with the agencies that are involved and confirmed that they have been paid all amounts that were due to them, yet we continue to show these items as outstanding or "Uncleared Transactions" in the Bank Account Reconciliation.  My questions now is how do I remove these "Uncleared Transactions" so they no longer show up as uncleared and at the same time I do not wake up the "Liability" past due error monster that pops up every time you tamper with anything in the liability section of QB. 

I have considered to simply "Void" or "Delete" the line items but I am not sure what the difference is between those two different actions.  So another part of my question is just that.  What is the difference between a "Void" or a "Delete" transaction of a payment and when is it appropriate to use this action.
