Thanks for visiting us again here in the Community, @nishajoeva.
I love to help you get this banking issue sorted out. However, I want to know if you receive any banking errors and what financial institution are you working with. Any further details would be a great help for me to narrow down this matter.
Moreover, the data we receive in QuickBooks depends on the information sent to us by the financial institution. If the connection between QBO and the bank is interrupted, online banking issues like transactions are not syncing may occur.
To fix this, you can manually update the account to refresh the connection and fetch missing items.
Here's how:
From the left toolbar, select the Banking menu and tap the Banking tab.
Click to highlight the account you're updating, then hit the Update button.
