Hello Debbie B,
Re 1882, please see 2015 Instructions for Forms 1094-C and 1095-C section Specific Instructions for Form 1095-C:
Part I—Employee
Line 1. Enter the name of the employee (first name, middle initial, last name).
Regarding the invalid characters, we are waiting for further guidance from the IRS as announced in the last IRS AIR webinar. Once we have more information, we will share with you.
Regards,
Margaret
