So you be clear, you're saying that the advice given in the thread I linked in my original post is incorrect. I believe you're saying I should follow the instructions in TurboTax to report a 1099-R for 2022 (although I won't get a 1099-R for the check I received for the excess until Jan 2024).
However, the instructions in the TurboTax modal mention nothing about line 5.
