Hi there, @tamar3. Welcome to the Community.
Could you please specify the type of data you imported into QuickBooks Online (QBO)?
QBO doesn't have a single place that shows the most recent import. To confirm whether your import went through, you'll need to review the data directly in the area where it should appear.
The most reliable way to confirm the import is to compare the data you imported with what's now showing in QBO, so you can be sure everything came through correctly.
If you have follow-up questions, please don't hesitate to Reply in the comments.
