I've been using Turbotax for years, but when it came to Capital Gains I've always had to attach a separate printed Quicken Report to my return that listed all the transactions, because there were too many to enter manually. This also meant that I couldn't file an electronic return because I didn't know how to 'attach' that statement to the Turbotax file.
(I've posted to this and other forums several times asking if someone knew how to import capital gains from Quicken into Turbotax, but have never gotten an answer. Maybe it's so obvious, nobody bothered to answer...?)
Anyway I discovered the following simple tip the other day so I thought I'd share it.
All you do is create a Capital Gains report in Quicken. Then you can 'export' that report to a tax file format, and next 'import' that file while running TurboTax! Turbotax then adds as many extra pages of capital gain transactions as required to get them all into your return.
I haven't tried, but I'd guess you can use this same trick to import many other types of tranactions that can be captured in a Quicken Report.
Enjoy...
