I'm here to lend a helping hand. If you're needing assistance with your May 2019 books, then you've come to the right place. To provide you with the best solution, can you clarify what you're needing help with inside of your books? (Reconciling, missing or duplicating transactions, etc) If you need help reconciling, follow the steps below.
Go to the Gear icon in the top right-hand corner.
Press Reconcile under the "Tools" section.
Select the account you want to reconcile by clicking the Account drop-down box.
Type in the Ending Balance and Ending Date from your bank statement.
Hit Start Reconciling when ready.
After you start your reconcile, I recommend to check out this link to walk you through the steps on how to receive a $0 difference and finish the reconcile.
