Retirement tax questions

OK...There may be an issue but it is beyond my expertise with early withdrawal exceptions from a Roth 401(k).   The code 1 in box 7 of the 1099-R would preclude having a Form 5329 included with the return.  However, having an amount in box 11 maybe a cause for an exception.

 

I will page one of our experts on retirement plans for assistance.

@dmertz User has a code 1B in box 7 with 2018 entered in box 11.  I have been unable to find any instructions in Form 5329 for this situation even though Code B specifically indicates Form 5329 if Line 11 of the Form 1099-R shows an amount.
