deceased filing with 1310

I have to file a 1310 with my Dad's return.  I want to make sure I file this the most efficient way as I still have not gotten the refund from last year's return.

I plan on mailing return along with form 1310.  But can I ask for the refund to be a direct deposit into my account, or any account for that matter?   Or do I need to ask for a check refund.
