I have power of attorney for my mom, who is incapacitated. The POA is in place at both the IRS and the California FTB. I have seen the instructions to send form 8453 to the IRS within three days of e-filing the federal return. Is there a form that I should send to the FTB?

Please see this FTB webpage for information about the California FTB Individual or Fiduciary Power of Attorney Declaration (FTB 3520 PIT).
