I am using a purchased turbotax. Form 1032 does not work. I know I must submit a paper return for my deceased partner and I am trying to submit efile for my return by filling out both returns on turbotax but only submitting mine by efile.

You have to file separate returns for you and your partner. In each return, you will report the eligible amount for a split pension. 

The final return for the deceased cannot be prepared together with a common-law or a spouse return.

I hope this was helpful
