First Aid found corruption for repair but First Aid from Recovery did not solve the issue
When repeated attempts to repair the filesystem fail, your next step is to back up all the files that you need and erase the partition.

Set up a new filesystem and then re-test the repair in recovery. If that fails - your hardware needs repair. If that succeeds with a clean check - you can set up a new account and/or restore from backup.

Live repair is not to be trusted, but live errors are of concern. I would try a verify in live mode to be sure you have issues before going to the erase / re-partition step as that can take some time so you'd rather be sure before starting down that path.
