Where do I enter a 1099-R from an inheritance?

My father passed away last year and he had an investment of some sort (I am not sure if it was an annuity, etc.) of which my brother and I were 50% beneficiaries.

 

I received a 1099-R for my 50%. It shows the total disbursement and a taxable amount (the two numbers are different because my father used post-tax money when he opened this so only the interest income was considered taxable.)

 

The logical place seems to be under "Retirement plans and social security" but when I go through this section the questions I'm presented with are treating the 1099-R as something from an account I opened.

 

Is there somewhere else I should be entering this income?
