Sounds like you are new to QMac. You will find the current reports and ability to print reports nearly useless. This alone has prevented me from upgrading. I still use QMac 16.
Diane, I'm not sure if you're coming from another version of Quicken, but there has not been capital gains report, per se, in QMac. However, a portion of the Tax Schedule Report does contain this information. When you run a Tax Schedule Report, click the Customize button. Set the timeframe as desired. Set the accounts to just Investment accounts to reduce other information on the report. Set the Categories and Tags to "None". (Hint: if you use "All", it will exclude uncategorized and untagged transactions, so you don't want to do that.)You can collapse the Schedules A & B sections and just view the Schedule D, which is capital gains. You can export the report to CSV (upper right) to open in Excel or Numbers and further format. Or you can export to TXF for import directly into tax software.If it's just a matter of viewing some of this info, you can look at the realized gain section within the Portfolio view. But unfortunately, this info cannot be printed or copied.
