Hello IRonMaN, thank you so much for your answer.

I followed the steps in that page (https://proconnect.intuit.com/proseries/data-conversion/) but the issue is in my 2021 Pro-Series Basic. I cannot see the import Client Data Conversion in Import Menu. However, if I open the Pro-Series Professional. That tool is available, but I bought the Basic Package. 

Thank you for your answer in advanced.
