Let me help reconcile your savings account in QuickBooks, tinalarkin.
Aside from the interest entry, you need to check if there are missing transactions or duplicates that won't make the balance to zero.
You need to compare each entry from the bank statement with the ones you have in QuickBooks. Doing this will make sure the saving account is balanced and accurate.
During the reconciliation process, go through your accounts in QuickBooks line-by-line, checking that individual item amounts and aggregate totals match what's on your bank statement.
Do this until the difference between the QuickBooks account and your bank statement(s) is $0. To prevent incorrect balance, you need to record transactions as they occur in real-time. Then, reconcile accounts frequently.
You also need to review the opening balance if you're reconciling for the first time. The amount should match your real-life savings account.
