see the 1040 Instructions at www.irs.gov for where to mail your tax returns.
mail each return separately.
if you elected the mail in option in 2016, then a paper return should include the required transaction detail report.
As critter would say, I doubt the IRS will make an issue of it if you leave out the detail report.
Are you expecting a refund ? You are coming up on the deadline to file 2016 return for a refund. So work on that one first.
