"Traditional IRA and Roth IRA contributions" section question with mega backdoor Roth in-plan

[windybird]

In Turboxtax, there's a section "Traditional IRA and Roth IRA contributions", where I am not sure whether I need to check the box for "Roth IRA" or not. I don't have any explicit Roth IRA account, but I have mega backdoor Roth in-plan conversion setup. 

Do I need to check the box for "Roth IRA" in this section? Or the mega backdoor Roth in-plan is for "Roth 401k" only, not for "Roth IRA", thus there's no need to check this box in Turbotax?

No, you do not check Roth IRA, since you did not make direct contributions to the Roth IRA.

Thank you!
