1041 box B override if zero K-1's

I have a complex trust 1041 with income being handled by the trust (no distributions) for 2021 (1st year of trust).   How do I make Box B of the 1041 denote zero K-1's attached (no K-1's since no distributions).  There are no K-1's being generated, but 2 beneficiaries.  There's no way to override the 2 in Box B.  If I delete the beneficiaries, then I get an error on the Fiduciary Info worksheet looking for Form 720 to be checked if I want to e-file (suppose I could just mail it?).

If I leave Box B as 2, do I need to generate and attach K-1's (zero distributions entries)?  How do I make TTB work for this?
