I'm pretty sure you're in the right place. It sounds like you were the (or one of) beneficiary of you Father's 401(k). A Form 1099-R is for a distribution of any sort from a "qualified" (retirement) account. The code in Box 7 of the 1099-R should be a 4 -Death. This indicates there is no early withdrawal, but since it was a 401(k) it will be taxable. Just enter it in TurboTax and the program will determine how much is taxable.
