You can paper file as long as it's less than 10 forms. The deadline for mailing is Feb 28th. 

Anything more than 10 has to Efile through the IRS's AIR system and the deadline is March 31st. You will need a separate TCC #. You can request a waiver but it's recommended to do so 45 days before the due date. 

There are options to file with a 3rd party. Just for a Google search.

A final thought is, is the Insurance carrier going to file? (It may be redundant),
