Answer:
Don’t confuse Reg B and Reg Z’s TRID rules. Without more information, I’ll narrow the answer to Reg B. In Reg B the bank defines what is an application and that can be very different than the TRID rules. If under Reg B the bank requires this additional information in order to have a complete application, then the bank doesn’t have that yet, this may be an incomplete application. (That won’t help you on TRID disclosures, however.)
