Thanks! I think I see what has happened now. The W-2 income my client had in prior years absorbed the entire business operating loss that would've shown up on Schedule 1.

Example 1040

W-2 Income:  $80K

Additional Income from Schedule 1: ($50K)

AGI:  $30K

Example 8995

Total QBI from S-Corp: ($50K)

QBI Deduction: $0

QBI Carryforward: ($50K)

Sorry guys. Have to spell this out, otherwise I won't remember it the next time it happens. Appreciate the help!
