Puzzled by this. It's really really unlikely that you got a ban for one editing error. You can see the list of blocks at https://www.openstreetmap.org/user_blocks and actual bans are only imposed for _repeated_ vandalism, edit-warring or copyright infringement. Short-term user blocks are generally imposed if the user isn't responding to attempts to contact them.

Do you have a link for your changeset and what happened?
