OK, I read your intro post where you outlined some of your investments. You must be getting killed on taxes because you have your investments in the wrong locations for tax efficiency. You wrote that you have blue-chip stocks in IRA and bonds in taxable. That is totally bass-ackwards. Put your bonds in the IRA and put equities in the taxable.
You should not have any bond dividend income on your Form 1040 Schedule B because it should be sheltered in your IRA. Your $990K of IRA money should be ALL bonds which is almost your total 30% allocation to bonds.
Your taxable accounts should have tax efficient equity funds. That is, funds that have almost no turnover and no distributions. That will be things like total stock market VTI and total international stock market VEU. All unrealized capital gains are tax-free and long-term cap gains are taxed at the very favorable long term cap gains tax rate of 15% nowadays. If you die all the investments get a stepped up cost basis and the gains are tax-free to your heirs.
You gotta do some reading: See

I think I just saved you about $50,000 a year in taxes.
