@SRL38 You're almost there!
You came up against what I'm presuming is an incorrect data validation format on the DE's TIN data field, invalidating EINs (and anything that doesn't comport with an SSN format).
To get the TIN of the disregarded entity correctly entered on Schedule K-1 H2, don't use Step-by-Step. In Forms view, open the Sch K-1 Wks and enter the correct EIN for the DE for each partner there. It will then correctly populate to the Schedule K-1.
This is a huge and blatant programming error. Anyone using TTB to file a form 1065 with partners that are disregarded entities is going to experience this problem, whether they know it or not.
