For clarity here - let's be precise in our terminology... we are only talking about an individual 401k and an individual roth 401k in the same "plan" with a major brokerage (the ones with the baby in the commercial).
There is NO Traditional or Roth IRA - so lets not confuse things.
That being said - the 1099-R issued by the brokerage has the rollover (conversion) amount in box 1, box 2a is $0.00, and box 7 is Code G. I inquired about this with the brokerage and they claim that their 1099-R is correct given that it is an "in plan rollover". Both they and I agree that it is taxable income, but that putting $0.00 in box 2a is consistent with IRS guidelines: (https://www.irs.gov/instructions/i1099r#en_US_2022_publink[phone number removed])
So when I enter the 1099-R in TurboTax, it questions me a couple times to be sure that box 2a is really zero. It then asks ""Is this a rollover from a 401k plan to a Roth 401k plan" which I check "YES" to...
My question where do I correctly document this in TurboTax so that it shows up as taxable?
Here is the response from the brokerage:
""
After reviewing your account, the transfer was a Direct In Plan Roth Rollover Request.
Customers that request to rollover assets from their Individual 401(k) account to their Individual Roth 401(k) account that was opened under the same plan is considered an In-Plan Roth Rollover (IRR).
Customers rolling over assets to their Individual Roth 401(k) account will generally include this amount in their gross income - very similar to a Roth Conversion. The rollover will not show as a taxable distribution or conversion. It is solely up to the customer to report any taxable portion of the IRR when filing their taxes.
