Even though some of the views, graphs and reports may lump dividend income from regular investment and retirement accounts together ... (which, I agree, they shouldn't)
Pull one of the Tax reports, e.g. Tax Summary or Tax Schedule. These reports know how to separate regular vs. retirement accounts and not report retirement account dividends.
On the Account Details page for an IRA investment in a mutual fund, when I check the box for Single mutual fund, it always reverts to "No". How can I fix it? Quicken Premier 2017 and Windows 10. I think this is causing the dividend income in this account to appear as dividend income (taxable) when it should be appearing as dividend income tax free.
