Can I contribute greater than my earned income to a Solo Roth 401(k) and a Roth IRA? TurboTax does *not* flag this as an excess Roth IRA contribution.

If I max out my Traditional Solo 401(k), TurboTax says I can't contribute to a Roth IRA as well since it exceeds my earned income. But it *will* let me exceed my earned income if I contribute to my Roth Solo 401(k) and Roth IRA.
