I am a military member who is registered independent, but I support Trump

I am stationed about 180 miles from my registered home of record

I requested a mail in ballot because there are exceptions on how far I can travel

I was able to get an exception approved and went to see my parents (both republican) and went to vote early in person (I received the same form both by mail and in person)

I voted approx 18 Oct in person and received the mail ballot on Sat Oct 31 to my current address

I am registered in the third largest metropolitan area of PA and the area was red in 2016 and has currently turned blue in 2020.

I have the mail in ballot in my possession, it was opened but I have made no marks on it.

Is there any suggestions on what I should do with it?
