I posted this in another thread, but I'll post it here also, in case it helps someone.
Regarding California's requirement that you write something like "Los Angeles County Fire" on the top of your 540: I discovered, at least in the desktop version of TurboTax, that when you do the walk through for California taxes, toward the end, in the "Other tax situations" section, there is an item called "Special Processing Conditions." When you click on that, first it asks you if you were out of the country on April 15 and on the next page it asks you if you experienced a disaster and there is a blank in which to enter the name of the disaster.
If you click on forms, you can see that TurboTax entered the name of the disaster under "Special condition text" in section VI of the Info Worksheet. And on the worksheet above the box for the disaster name it states "prints at the top of form 540," which is exactly what California says you should do.
So TurboTax (at least desktop version) does handle this. I don't know about for other states, but at least for California I can verify this. I also don't know if this works in the online version.
