If my sports season is in the spring (2021), can I include that I've participated in that sport when

I’ve played varsity softball at my school for three years. I am applying for colleges and I want to indicate that I have done it for all four years of high school. Since college applications will be finished by this coming fall/winter, I wouldn’t have experienced my fourth season of softball by then (my season starts in February). I know for sure that I will be playing the sport for sure…

Am I allowed to check off that I did softball for all four years of high school on the Common Application even though I haven’t technically finished the fourth season by that point in time?

My kids included their Spring sports as part of their 12th grade activities and used the “description” space to clarify.
