Will I get arrested for voting in an illegal matter?

I got a ballot in the mail written under my name more than one week ago before we headed on our way to vacation. I thought I left my ballot on the table. But nope, my stepdad allegedly threw the ballot away in the trash and I asked him where it was, he apparently didn't have a clue. My mom finally gave me hers since she hasn't voted since the first Obama era and that she isn't into politics. I voted, and I also turned in my ballot via the mailbox (also my first time voting by mail).

I felt like an even bigger idiot just realizing after I signed that my mom's electronically written name was on the envelope AND that I wrote my name and signature on top and my signature in the middle just above my mom's name. Basically, "if the voter is unable to sign" I got to be her technically-unauthorized voting assistant, literally voting as the son of the "voter".

I don't feel like "our" vote is going to be counted. My envelope for my own ballot that I was supposed to have is gone forever! Nowhere to be located in our house.

It's October 23rd and the voting ballot will be casted a few days after November 8th.

I am from California.

Yes, either prison, jail, or probation
No, but I'll assure you that was pretty risky
No, you're innocent
