Brandi417! Think I figured out a solution. I updated my main post.
Good luck.
I had old versions (Turbotax 2016-2018 installed, not sure if related) that were still on my PC.
1) I uninstalled them.
2) I uninstalled Turabotax 2019 and did a fresh install. I got further this time around but found an error message with "wcaiper". Didn't know what it was.
3) Googling around I found this thread:

I ran through the solutions.
The "Microsoft Fix-it Tool" did it for me. I selected I had an "installation" problem and selected "wcaiper". It uninstalled it for me.
I re-ran Turbotax 2019 and NOW my California downloaded properly and shows up.
Good luck to everyone else who needs a solution.
