Reconciling Quickbooks Balance

[George Smith]

Good afternoon,

Ive got a quick questions regarding reconciling on quickbooks. I just signed up for QB and all of the info has been imported and categorized for 2018.

When I go to reconcile, It lists a starting balance which was not the starting the balance on 1/1/18. It lists the balance of the checking account on 9/5/18. 

Can i reconcile the whole year at once.. 1/1/18 to 12/31/18/? Why does it not show the starting balance on the day earliest day 1/1/18 of transactions that were imported?

Thanks,

George
