Should I enter my name as the person that the IRS can contact about the return?
Your address should be on 1040 so IRS mail, including refund, will go to you.
using the contact line won't hurt.
And is there somewhere I am suppose to sign? I only see a place for her signature.
Sign with
"<your name> as personal rep"
OR
"<your name> as executor"
according to your status.
