All of the inputs are 1.

The 1040 shows the checkbox that indicates they are eligible for the child tax credit.

I followed the instructions and put a -1 in for the recovery rebate screen, indicating no advanced credit was received and it still won't generate the 8812. I also tried leaving the recovery credit input blank and still it won't work.

The parents and dependents have SSNs and I marked the ID as verified for the parents.

Something in Proconnect's undocumented, crappy code is preventing the credit, but nothing is showing up in the diagnostics.

Any ideas?
