In 2023 I did an in-plan 401K to Roth 401K conversion. There was a small amount of after tax money in the 401K so I rolled it over first. The 1099-R from my former employer says that all the dividends from the Roth 401K were taxable. I have two questions: 1. Though the 401K was started in 1998, is 2023 considered to be Year 1 for the Roth 401K in **TurboTax** (it is the first year for IRS) even though it ISN'T the first year I received income from the payer? (I received 1099-R forms from the payer for a decade for the 401K). 2. I assume that the dividends are taxable because the 5-year period is not yet met but are they still taxable in full as the 1099-R says even though some of those dividends are on after-tax money rolled over to the Roth 401K? How do I indicate that some of this was income from after-tax money or subtract the relevant amount of dividend (and explain)? (Note: I am over 60 years old.)
