Will the state of California be able to see this TurboTax PDF attachment or do we need to print and mail a duplicate California state return with all the FTB 3840/Schedule A's?
Please advise since I will need to snail mail it ASAP if necessary.
I highly recommend that you print and mail your CA return ASAP.
There is simply no guarantee that the combined attachment will be in a format that the CA FTB will be able to read (by machine, most likely) or if the attached CA forms will even make it to the FTB at all.
The safest approach would be to mail the CA return.
