I have input co cars (1A NIC), health insurance (1A NIC) and subscriptions (NIL) for employees that require input and when I print the P11d to check with individuals they are happy with details I am providing I noticed that in section N the box is ticked with an X for some employees and a Y for others although I haven't added anything in this section?   This didn't happen last year.  Should this be happening as seems to have happened automatically and how do I know which should be X and which should be Y if should be there or how do I remove if it is an error on the software?
