I'm not a PS user. Do you know that it is available?

How to find release dates for forms and schedules in ProSeries

Dear God, please send someone to help me.

By the way, may I enter '100W' in the upper right corner of Form 100, as there is a Sch R 1-7 in the system and a light yellow box in the exact location where I can enter 100W in the blank box?

I believe that 100W is NOT a form PS will generate.

Complete a pdf https://www.ftb.ca.gov/forms/2024/2024-100w.pdf and file according to the instructions for the form. 

It looks like a huge surprise. Proseries Professional has not solved the problem for so many years.

This is part of why Intuit has so many offerings. That form is available in Lacerte and ProConnect. Google tells me that even TurboTax Business.,

You can post that as an idea to add to Proseries at https://accountants.intuit.com/community/forums/postpage/board-id/603/search-before-post-mode/true
