Retirement tax questions

@dmertz @sg14d  Just to clarify, as far as filing a 8606 for a non-spousal inherited IRA with a basis, I understand that Turbotax won't prepare it, but will allow entry of the pro-rated basis so that it is correctly subtracted from the distribution.  Can you still e-file the return and mail in the paper 8606 separately and by itself (which you prepared outside of TT)?
