Roth Conversion Confusion

This year we did a Roth conversion for my wife. When entering the information I received a couple of questions that puzzled me.

Firstly, when entering the information it continually references MY name as the IRA holder and I cannot find how to enter the conversion info for my wife's IRA. Is this because I am the primary tax filer?

Secondly, the software asks for the total value of all my traditional IRA's, excluding the Roth.

  - Why is this relevant when other IRA's are not being touched?

   - Is this just for the accounts in the name of the person doing the conversion, or husband and wife combined?

 

Thanks for any help you can offer.
