Concurrent e-filing return and mailing TT unsupported form available on the form's website

Can I e-file my TT tax return and mail Form 8990 that TT does not support, but I found on the form's website?

@jose37jr , while you can indeed e-file and also send the form 8990 by mail and hope that the two sets get together somewhere in the IRS labyrinth, my strong suggestion would be  to instead  send everything by mail.  You want to make sure that the return and this extra form 8990 are processed as one entity. 

Does this make sense ?   Is there more I can do for you ?
