I tried the suggested method of just selecting the transactions within the statement period ...  Was not pleased with the outcome.  We started using QB on 2004 so there was an incredible number of uncleared transactions prior to the statement period it made the detail reconciliation reports hundreds of pages long and confusing because it was listing transactions as uncleared that had actually cleared the bank.  I knew that going forward the reports would always be troublesome and confusing for our employee that is responsible for reconciling the account.  After much thought I undid the previous reconciliation, removed the journal entry that I had created for the beginning statement balance for December, left the balance as $0.00 and used the ending balance on the December 2019 statement for the first reconciliation.  I hid all of the transactions prior to the December statement end date.  I selected the "mark all" tab and then  unchecked all of the transactions I knew to be uncleared as of December 31.   I was very pleased with the outcome, the difference was only $567.40.  I made a $567.40 journal entry debiting the bank and crediting misc expense which brought the difference to $0.00.  Now we are starting with a clean slate for 2019 year end!
