What year are you doing - 2019 or 2020? 2020 1099-R's have not even been sent out yet - do you have your 1099-R? What code is in box 7?
For a designated Roth (401(k) Roth) box 5 will be the amount of your contributions that are included in the box 1 amount so it is not possible to include more than the total of box 1. If box 5 is actually more then box 1 then the 1099-R is incorrect and must be corrected by the issuer.
In most circumstances a 401(k) Roth will not have a blank box 2a - again what is the box 7 code?
