In my opinion, the plant is way too young for identification. They tend to show their real characteristics when they have some size, planted in the ground. So far it looks just like my "musa helen" of the same size. But I suppose it could also be cheesmani or nagensium, or anything with a waxy pseudostem. It is not likely to be clean nagensium, since clean nagensium seeds are not on the market these days (and are supposed to be white?).
Unfortunately I do this all the time. Plant seeds/seedlings and forget to label. Once, I thought I had sprouted 100 itinerans when in reality it was regular ornata! Illustrates the importance to label what you plant! In the past years I have gotten better though!
