How Do I Get TurboTax to Register the After-Tax Contribution to My 401K Rolled Over to Roth IRA (a so-called "Mega Back Door Roth Contribution")?
TurboTax is not registering my after-tax contribution to my I-401K-Regular.
My I-401K was empty.
I put $10,919 in as an "employer", after-tax, contribution. I have an LLC with pass through taxation to me individually so I paid income tax on this amount prior to its contribution.
Now when I try to enter my 1099-R which Vanguard provided, I cannot get TurboTax to register the after-tax contribution.
On my 1099-G
1. My Box 1 Gross Distribution is $10919
2. My Box 2a Taxable Amount is $10919 ( Vanguard says they have to list it this way because they don't keep track of whether "Employer contributions" are post-tax or pre-tax. Very frustrating.)
3. Box 5 is empty (Again, Vanguard says they have to list it this way for the reason above).
4. Box 7 is G
When I enter it into TurboTax, TurboTax asks:
1. Was this money rolled over to a Roth IRA? I say "yes".
2. Did I make after-tax contributions to my 401K? I say "yes".
3. A screen comes up asking the list the amount of the after-tax contribution? I enter "$10,919".
But it still assesses me tax as though the rollover was of a pre-tax contribution.
It thus appears not to be registering that the after-tax contribution should register as non-taxable in the rollover to Roth.
How do I get it to register that this is after-tax funds and thus should not be taxed again?
