Qualified Business Loss Carryforward

I have $34,789 in QB Loss Carryforward with a postive profit for my business of $5,275 + taxable income of $34,395 and a tax liability of $5,041 resulting in a balance due of $2,069.

 

Question: How can I use my QBLCarryforward to reduce my tax liabity?

Question: Do I wipe out the taxable income or tax liability amount on Schedule 1 line z?

Question: How do I reduce my QBLCarryfoward from the amount on Schedule 1 line z?

 

Thank you!
