So at risk of concernfagging:

I requested an absentee ballot this year but haven't sent it in because I am opting to instead file a real ballot on Tuesday. My concern is in the fact that I have been getting inundated by letters telling me that it is a matter of public record that I have not submitted my absentee ballot yet.

So let's say I never vote on Tuesday. Couldn't some party see on Wednesday that I never voted and never submitted an absentee ballot, then submit one for me without my permission?

One vote is nothing but let's say there are thousands of people like me, or more. Is this something to be concerned about?
