Partner loss limited by Basis

[jgcpa]

Partner has ordinary business loss suspended in 2020 due to basis limitation. In 2021, there is some tax exempt PPP income, and ordinary business loss. Losses are not fully deductible in 2021 due to basis limitation. The k-1 has business interest expense code N. The partnership is not subject to 163(j). Do I need to proportionally allocate basis to ordinary business loss and the new loss class ( business interest expense)? And if yes, would Sch E page 2 have separate lines for ordinary business loss and a separate line for business interest expense since they are separate loss classes?  Snippets from Checkpoint for reference: a pro rata share of each loss class (based on the amount of loss in that class compared to the total loss) is currently deductible and the rest carried forward. To enable partners to track the items in this new Section 704(d) loss class, the 2020 Form 1065 instructions provide that, for tax years beginning after November 12, 2020, partnerships will be required to report to their partners on Schedule K-1 the amount of deductible business interest expense that is included in other income or losses reported on the Schedule K-1,
