To get help by speaking to out QuickBooks Care team, you can choose to chat with us, request a callback or get the phone number in the Help icon. They have the tools to pull up and verify your account. Community is a public space, we have limited tools to do that. Although, I can help you to bring your latest bank transactions in QuickBooks Online.
First, you can trigger the bank connection to QuickBooks by clicking the Update button. I added a screenshot for additional information.
Then, If you're still not able to get the latest bank transactions, you can go to your bank website and then download the latest transactions. Use these file types to upload the bank transactions smoothly when you are in QuickBooks:
CSV - Comma-Separated Values
QFX - Quicken
QBO - QuickBooks Online
Once done, you can now upload your bank transactions in QuickBooks Online (QBO). Here's how:
Go to the Gear icon, under the Tools column select Import data.
Choose Bank data then, click the Browse button and select the downloaded transactions from your bank.
Follow the on-screen instructions and then confirm the upload transaction.
