When doing a 2018 Roth IRA recharacterization to a Traditional IRA, do the earnings get included as part of the Traditional IRA contribution?

The Roth recharacterization amount is less than limit and I want  to make another Trad IRA cont (before tax deadline) so that total is 6500. Does the earnings from the Roth rechar count towards the Trad IRA contribution?

We contributed A to Roth, and recharacterized all to Traditional so A + B earnings. I want to then contribute C so that total for 2018 is the limit, D (6500). Does C=D-A-B or C=D-A? 

And in TurboTax Premier, for the Traditional IRA "Tell Us How Much You Contributed" page what do I put into the "Total 2018 Traditional IRA Contributions" box?
