Trying to confirm NOL Carryforward works differently than Cap Loss Carryforward when TP has minimal income. 

Simple example: 

2023 TP business income = $15,000

TP is 65 yr old single, std ded = $15,700

2022 TP NOL carryforward = $20,000

NOL deduction limited to 80% of income = $12,000

So AGI = $3000 and taxable income = 0

But taxable income would've been 0 even without the NOL. 

So does the NOL carryforward for 2024 = $8,000?

Or does the NOL carryforward stay at $20,000 (like an unneeded Cap Loss carryforward)?

Hope that makes sense. Thanks for any clarification.
