K-1 with multiple sub-businesses

[MBSC]

Hello.  I have a single K-1 for Company A and it shows -$1,338 of ordinary income in box 1.  In the 199A detail section/statement associated with Box 20 on the K-1, Companies B, C, D are listed with -$593, -$219, and -$526 of qualified business income, which totals the -$1,338.  [None are SSTB businesses....]  TT only allows one of the B, C, D entities to be input.  Do I need to bother with the exact 3 way allocation and if so, how do I do it?  Thank you.
