Can I piggyback off this question and ask a similar question?  It's kind of backwards from this question.  I received access to a QBO account and was asked to reconcile the year 2015 (and potentially I'll be able to work on 2016-2018 if I can finish 2015 timely).

I was told that the tax return was finished for 2014 and tied to the 2014 QBO and that now cleanup was necessary for the subsequent years.  So I began to reconcile 2015.  All of the transactions were entered for each year so it was only a matter of reconciling the bank account.   I was also told that there might be differences and to just put them to a suspense account for review.  When I reconciled January, the beginning balance was off, but I made an entry to the suspense account to move forward.  I finished January and then reconciled February and there were no other problems with either month.

But, when I began to reconcile March, there were not many transactions in the Reconcile screen so I looked in the bank register.  I saw that most of March through July transactions had "R" beside them.  At first I thought someone did that by mistake, but there were too many of them.

I then looked in the audit log and realized that the account had been converted from desktop during 2018.    So I assume many of the months had been reconciled in desktop, but all the past reconciliations are gone.  How do I undue those reconciliations?  I can't re-do the bank reconciliations when the transactions are not in the reconcile screen.

Do I have to go through the register line by line and remove the "Rs" so that I can reconcile? (there are over 300 transactions each month!)

OR, instead of re-doing all of the bank recs, should I continue with the reconciliation process in the first month without any "Rs"?  The months of August through December have no "Rs".

I copied the entire bank register for the year, which indicates which items have "Rs", so maybe continuing with the process in August would be the better idea.

This is an old post so I might not get an answer, but I hope you see it and are able to respond. 

Thank You!
