Is the income on my 1099-R form nontaxable on our joint return with my deceased husband if Box 7 code is "4" (death) as I inherited this 2017 RMD along with his IRA?

[Nokomis--FL]

yes, and I don't turn 70 1/2 until 2018.On the same day as his death, Jan 1 2017,the first of our 12 pre-set monthly withdrawls was made. These more than cover the RMD and taxes on an annual basis.
Please remember that I'm asking this from Turbo Tax. I haven't seen an income tax form yet, so I haven't a clue what lines 15a and 15b are or what they read, until its complete. I've questioned ths in process

I should state that although I rolled over my husband's entire IRA accounts, we took and I will continue to take annual withdrawls, at least as much as the RMD. This, and Social Security, is what we live on.

You can view the 1040 form using the Tools, summary, and then preview 1040 in the left column.

If you turned 70 1/2 in 2018 then no RMD was required in 2017.

You said:  "Jan 1 2017,the first of our 12 pre-set monthly withdrawls was made." why was that?  Is there a separate 1099-R for that?  Whose distribution was that?

It is still not clear what was done with the money in box 1 on the 1099-R.

Was some of it put into your own IRA and some kept?   If you did that then this can get complicated because TurbpTax does not support doing two different things with the money form a single 1099-R with a code 4.  It must either all be rolled in to a IRA or your own, or all kept - but not some of each.   That would require breaking the 1099-R into two 1099-Rs and entering each separately.   Reporting that to the IRS can be difficult when there is box 4 withholding.
