a QBI loss can only be used to offset QBI income for the QBI deduction. It does affect regular income taxes unless you have a net QBI deduction on line 13 of the 1040. if you had no QBI income the loss carries forward indefinitely. The QBI loss carryforward can differ from NOL or passive loss carryovers because of how each is computed.
you may find it on the carryforward worksheet but it may also be reported on the activity worksheet.
