It does auto-populate but what the form populates with depends on whether or not you qualify for an exception to the penalty and whether or not you opted to annualize your income when you went through the CA state interview questions.
Click on Forms in the upper right corner and scroll down the list of forms to the CA forms (bottom of the list) and see if Form 5805 is on the list. If it is not in the CA list of forms, you are not required to file the form, but you can still view the form and details. Click on Open Form (next to the Errors button) and type in 5805. Click on the Form 5805 and select Open Form to see the details. You can edit the form here also.
If you meet any of the following 3 conditions, you do not owe a penalty for underpayment of estimated tax. Do not complete or file the form if:
•• The amount of your tax liability (not including tax on lump-sum distributions and accumulation distribution of trusts) less credits (including the withholding credit) but not including estimated tax payments for either 2018 or 2019 was less than $500 (or less than $250 if married/RDP
filing a separate return).
•• Your 2018 return was for a full 12 months (or would have been if you were required to file) and you did not have any tax liability on that return.
•• 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.
