New client checklist. I saw this list on the two day ProAdvisor training on the 5 & 6. I am reading about it in training here. How do I locate this list?

Do you mean the new "Overview" screen? That's the top item in the front page when you access a client's books in QBOA

Did you ever end up locating it?  I am also trying to find this, after going through the training, and would appreciate any assistance.

You can find it in the Marketing Hub under Onboarding clients.  They have some fantastic resources there!  https://quickbooks.intuit.com/accountants/resources/marketing-hub/

New Client Checklist can be found via this path QB Accountant >> Pro Advisor >> Workflows for onboarding clients into OBO >> Onboarding clients who are new to QBO >> Meet the client and gather information dropdown, >> Click on New Client Checklist in blue and download. 

Hope this helps
