Hi @SMS55SIR,

Welcome to the community and thanks for posting your first questions. Have you tried reaching out to our support? If not, here is the How to contact them:

How to contact ProConnect Tax for help

https://accountants.intuit.com/support/en-us/help-article/intuit-account-settings/contact-proconnect...

Also here is a support about the partner's percentage not equaling 100% that might help:

Troubleshooting partnership diagnostics ref. 334, 335, 25286, and 35624 in ProConnect Tax

https://accountants.intuit.com/support/en-us/help-article/partnership/troubleshooting-partnership-di...

For the .CSV, I believe that is excel converting long numbers to scientific notation.

Hope this helps and happy posting!
