When we were going, the weekend before my partner got exposed to COVID while out of town, but I still wanted to go. After a horrendous experience with TM with Darren Criss' Christmas show, I opted to skip SeatGeek and went to Jujamcyn, found their customer service email, and explained my case. They went ahead and refunded one of our tickets. (My guess is because we bought good seats and that single could resell at a higher rate, but I didn't ask.)
