Timely Filed 83 (B) w/in 30 day period

I filed by 83 (b) election form 9/9/2020 and the deadline was 9/18/2020. I just received confirmation of the filing and it was stamped as being received 10/02/2020by the IRS.

My company acknowledged its receipt on 9/14/2020.

What can be done about this?

Thank you
