Thanks for your reply @LeticiaF1. Reviewing the 1099-R instructions, I note that the term "timely" does not appear in any context specific to Roth's. There are instructions requiring an attempt to compute earnings on Roth withdrawals:
... for the distribution of excess Roth IRA
contributions, report the gross distribution in box 1 and only
the earnings in box 2a. Enter Code J and Code 8 or P in
box 7.
To the question of which code should be used, there is this:
Use Code Q for a distribution from a Roth IRA if you know that the participant
meets the 5-year holding period and:
• The participant has reached age 591/2,
• The participant died, or
• The participant is disabled.
Note. If any other code, such as 8 or P, applies, use Code J.
I read the above as requiring both codes 8 and J required, if claiming a timely withdrawal.
I am wondering if the 1099-R instructions generally assume timely corrective withdrawal is being claimed, since from what I have read elsewhere, a untimely withdrawal amount should equal the original contribution -- with the 6% penalty charged according to rules laid out elsewhere. A recent confirmation of that from a custodian of Roth IRAs:
Untimely corrections must be reported on IRS Form 1099-R as an early or normal withdrawal, depending on your age.
Where for someone over 59 1/2, a "normal withdrawal", is presumably code Q.
