DawnC,
Your last bullet is not quite right, see: https://www.ftb.ca.gov/forms/2019/2019-5805.pdf
"The amount of your withholding plus your estimated tax payments, if paid in the required installments, is at least 90% of the tax shown on your 2019 return or 100% of the tax shown on your 2018 return (110% if California adjusted gross income (AGI) was more than $150,000 or $75,000 if married/RDP filing a separate return) and you are not using the annualized income installment method. Taxpayers with California AGI equal to or greater than $1,000,000 (or $500,000 if married/RDP filing a separate return), must use the tax shown on their 2019 tax return if they do not meet one of the two conditions above."
And I am finding on my return that TT correctly flagged the need for IRS Form 2110 and a Federal penalty because I paid 100% but less than 110% of my TY2018 Federal liability, but it is NOT flagging the need for a CA FTB Form 5805 for similar conditions on my TY2018 CA liability. I think this is a bug in TurboTax 2019.
