Hey there, silva-donna-hotm.
Welcome to the QuickBooks Community! I'd be happy to guide you in the right direction for the best assistance.
If you're using a third party app, and you're unsure of how to import your data, you'll need to reach out to the Apps support team. They'll be able to provide the necessary steps on how to import data from within the App. You can also manually import data by following these steps:
1. Head to the "Gear" icon
2. Select "Import data"
3. Choose the data you'd like to import
Here's a guide for reference.
If you have any other questions, feel free to reach back out here.
