You only report IRA withdrawals on your tax return if you are the owner (or your spouse is the owner and you are filing jointly) or you are the beneficiary of an inherited IRA. If you are being asked for the date of death of the prior owner, then Turbotax thinks this is an inherited IRA. That is normally indicated by code "4" in box 7 (it can be combined with other codes). If this is not an inherited IRA, double check your 1099-R and your entries in turbotax. If the 1099-R has code 4, you need to get a corrected 1099-R from the payer.
