What information are you trying to import? More details would help so we can continue with the steps.
If you're trying to import your bank transactions, you'll want to ensure your file is formatted properly. This ensures there will be no errors when importing. You can check this article for the steps and details regarding the template: Import bank transactions using Excel CSV files.
If this isn't the case, are you referring to your lists such as customers, products, services, etc..? You can use our Import data tool to bring them in. Here's how:
Click the Gear icon, and choose Import data.
Select a specific list you want to import.
Browse for your file, then hit Next.
Map your fields then continue with the import process.
