1099R state tax withheld

I contributed 6000$ to my traditional IRA and then did a backdoor roth with TDameritrade  To do the conversion 240$ was NC state withheld.  So I recieved 2 different 1099-R forms,  one with distribution of $5670 with box 14 blank (no state tax wittheld) and the other with a distribution$240 box 14 -$240 state tax withheld and state distribution $240.  

Turbotax detected it as 2 different 1099R.  is that right or should I just combine them and put in the state tax withheld and the state distribution as 5760?

 

Would my Roth contribution still considered to be $6000 or 5760 as far form 8606?

 

For the $240 distribuition/tax withheld Turbotax asks me what I did with the money?  move it to another retirement account or something else.  would the tax withheld be the something else?

 

Appreciate the help.
