I do not believe this input screen applies to a Roth IRA. By definition, all contributions to a Roth are post-tax and an entry screen for post-tax contributions for Roths would be redundant. Please note that this is an Inherited Roth IRA, and this input screen, which is intended for post-tax contributions to non-Roth IRAs does not apply. Additionally, if one were to try to use this screen as proposed, this is an inherited Roth IRA, and, thus, the post tax contributions would have been made by the deceased, not the recipient. Therefore, the input for the recipient still would be zero and not resolve the issue.
