I would have interpreted the product comparison chart as indicating that tax lots are only tracked if you purchase the Premier version.
@johncros - If the Schedule D report which can be uploaded into Turbo Tax is important to you then you will want Premier. But if uploading into Turbo Tax is not important to you, both versions have the Capital Gains report which provides the same data in a little different format.
@Chris_QPW - Well, how about that. I learn something new everyday. I personally never upload anything from Quicken into any tax software since I don't trust the accuracy of the data to be good enough for tax purposes without extensive manual review and I think it's much better to rely on the tax forms from the brokerages but if I ever do it's good to know this.
