Two current licenses. What do?

I paid for a year license ending 2027-02-17.  I then won a contest, the prize being a one year license.  I was told I had to redeem the code before april something.  I did, and now I have two (slightly different) licenses running at the same time.  I'd really really like to stack them end to end because I have only one brain, two hands, and one seat.

I could not see a way to pause one license or other similar reasonable actions from the license management panel in my account.

What do?  

Thank you,
